Climate Change and Its Impact on Biodiversity

1. How Global Climate Change Affects Various Ecosystems and Species

Terrestrial Ecosystems:

  • Forests: Increased temperatures and changing precipitation patterns can lead to more frequent and severe forest fires, insect infestations, and diseases. For instance, the pine beetle epidemic in North American forests has been exacerbated by warmer temperatures, resulting in widespread tree mortality.
  • Grasslands and Deserts: Shifts in climate can alter the composition and distribution of plant species, affecting the herbivores and predators dependent on them. Prolonged droughts can lead to desertification, further reducing biodiversity.

Inorganic Chemistry

What is Esterification Reaction?

When primary alcohol is treated with a carboxylic acid in the presence of sulphuric acid a compound is formed. This compound has a sweet smell. The compound obtained is called ester. The chemical reaction occurring in the formation of the ester is known as an esterification reaction.

CH3COOH + CH3CH2COOH → CH3COOCH2CH3

Esterification Mechanism

This process involves five steps. We have discussed the steps below:

Step 1: Cation formation

Esterification Mechanism

Step 2: Delocalized carbocation

Carboxyl oxygen gets protonated to give delocalized carbocation making the carbocation a better electrophile.

Esterification_Mechanism_step_2

Step 3: Transfer of proton

A proton is transferred to one of the hydroxyl groups to form a good leaving group.

Esterification_Mechanism_step_3

Step 4: Formation of the pi bond

The hydroxy group’s alcohol oxygen atom donates a pair of electrons to a carbon atom which makes a π bond by eliminating water. The concentration of water is less than methanol, therefore, it is not a feasible nucleophile to reverse the reaction.

Esterification Methods

Esterification can happen in three ways. They are discussed below:

  1. From acid anhydride and alcohol
  2. From acid chloride and alcohol
  3. From carboxylic acid and alcohol

1. Acid anhydride and alcohol

The reaction between alcohol and acid anhydride is comparatively slower when compared to acid chloride. To get a number of esters it is required to warm the mixture. For instance, consider 2,6-diiodophenol.

2,6-diiodophenol reacts with an acid anhydride to form ester.

Acid anhydride and alcohol

2. Acid chloride and alcohol

Esterification process can also be performed with alcohol and acid chloride at room temperature. Ester is obtained with steamy acidic fumes of hydrogen chloride. For instance, benzoyl chloride.

Reaction of alcohol and benzoyl chloride to form ester.

Acid chloride and alcohol

3. Carboxylic acid and alcohol

Production of esters from carboxylic acid and alcohol. Heat them in the presence of acid catalyst such as sulphuric acid (H2SO4) is used as a catalyst. For example, reaction of ethanoic acid and propanol to form propyl-ethanoate and water.

Carboxylic acid and alcohol

Properties of Esters

  • The name of an ester is derived from its carboxylic acid that takes part in the esterification reaction.
  • They have a pleasant smell.
  • They have a wide application in the perfume and food industries.
  • Esters are organic compounds found in oils and fats.

Uses of Esters

Some common uses of esters are mentioned below.

  • Esters that have fragrance are used in perfumes, food flavourings, and cosmetics.
  • Used as an organic solvent.
  • Nitroglycerin is known and famous for its explosive properties.
  • In the manufacturing of surfactants like detergents and soaps.
  • Natural occurring esters are present in pheromones
  • The backbone of DNA molecules is formed by phospo esters.
  • Polyesters are used in the production of plastics

Organic Chemistry

Organic Chemistry
Organic chemistry is the study of compounds
containing carbon with the exception of simple
compounds e.g. carbonates (CO3
2-), carbon
dioxide (CO2) and carbon monoxide (CO).
Nomenclature
There are over 6 million known organic
compounds. Nomenclature is therefore very
important.
Here are some basic guidelines that should help
in the naming of the simple compounds you will
come across during this course. You will get
practice at this in your tutorials. 

Physical Chemistry

Terms in thermodynamics
System is the part of the world which we have a special interest in, e.g. a
reaction vessel, an engine, an electric cell.
 There are two points of view for the description of a system:
Phenomenological view: the system is a continuum. This is the method
of thermodynamics.
Particle view: the system is regarded as a set of particles, applied in
statistical methods and quantum mechanics.
Surroundings: everything outside the system.
Isolated system: neither material nor energy cross the wall

Economics

Economics is a social science that studies how individuals, businesses, governments, and societies make choices about allocating limited resources to satisfy their unlimited wants. It encompasses various aspects such as production, distribution, and consumption of goods and services. Here’s a detailed overview of its key components and concepts:

1. Basic Concepts

  • Scarcity: The fundamental economic problem of having limited resources to meet unlimited wants.
  • Opportunity Cost: The cost of forgoing the next best alternative when making a decision.
  • Supply and Demand: The relationship between the availability of goods and services and the desire for them, determining prices in a market.
  • Marginal Analysis: The examination of the additional benefits of an activity compared to the additional costs incurred by that same activity.

2. Branches of Economics

  • Microeconomics: Focuses on individual and business decision-making processes, market mechanisms, and the effects of government policies on specific markets.
  • Macroeconomics: Deals with the economy as a whole, studying aggregate indicators such as GDP, unemployment rates, and inflation, and the impact of monetary and fiscal policies.

3. Economic Systems

  • Market Economy: Economic decisions and pricing are guided by the interactions of citizens and businesses.
  • Command Economy: The government makes all economic decisions and controls all the social and economic activities.
  • Mixed Economy: Combines elements of both market and command economies, with varying degrees of government intervention.

4. Key Economic Theories and Models

  • Classical Economics: Emphasizes free markets, the role of competition, and the idea that economies are self-regulating.
  • Keynesian Economics: Focuses on total spending in the economy (aggregate demand) and its effects on output and inflation, advocating for active government intervention.
  • Monetarism: Highlights the role of governments in controlling the amount of money in circulation.
  • Behavioral Economics: Studies the effects of psychological, cognitive, emotional, cultural, and social factors on economic decisions.

5. Important Economic Indicators

  • Gross Domestic Product (GDP): Measures the total value of all goods and services produced within a country.
  • Unemployment Rate: The percentage of the labor force that is jobless and actively seeking employment.
  • Inflation Rate: The rate at which the general level of prices for goods and services is rising.
  • Balance of Trade: The difference between the value of a country’s exports and imports.

6. Policy Tools

  • Monetary Policy: Managed by central banks, it involves controlling the money supply and interest rates to influence economic activity.
  • Fiscal Policy: Involves government spending and taxation decisions to influence the economy.
  • Trade Policy: Includes tariffs, trade agreements, and quotas to regulate international trade.

7. Global Economics

  • International Trade: The exchange of goods and services between countries, driven by comparative advantage.
  • Globalization: The increasing integration of economies, cultures, and institutions across the world.
  • Development Economics: Focuses on improving fiscal, economic, and social conditions in developing countries.
