Question 1.
Write an essay on the harmful effects on the human body and the social issues caused by the use of ethanol as a beverage.
Answer:
Ethanol, while socially prevalent, carries significant risks. Physically, even short-term use impairs
coordination and judgment. Chronically, it damages the liver, brain, heart, and digestive system, increasing the risk of various diseases and cancers. It also weakens the immune system.

Socially, alcohol fuels addiction, leading to individual struggles with finances, relationships, and mental health. It contributes to domestic violence, child neglect, and family breakdown. On a broader scale, alcohol is linked to increased crime rates, drunk driving, and a substantial burden on healthcare and public safety. The normalisation and marketing of alcohol often mask these dangers, contributing to its widespread misuse and the resulting harmful consequences for individuals and society.

INTRODUCTION

Organic compounds undergo a variety of chemical reactions. Substitution reactions involve the replacement of one atom or group with another. Addition reactions occur when new atoms or groups attach to unsaturated organic molecules. Thermal cracking is the process of breaking down large hydrocarbons using heat. Polymerisation is the joining of small organic molecules (monomers) to form large chains (polymers). Combustion is the exothermic reaction of organic compounds with oxygen, releasing energy.

Several organic compounds have significant commercial importance. Ethanol is used as a solvent, fuel, and in beverages. Methanol is an industrial solvent and a precursor to other chemicals. Ethanoic acid (acetic acid) is the main component of vinegar and is used in various industrial processes. Esters are responsible for many natural and artificial fragrances and flavours.

Organic compounds also play a crucial role in medicines, with their diverse structures allowing for specific interactions with biological systems to treat diseases.

POLYMERISATION
Polymerisation is the process by which simple molecules join together to form large complex molecules. The simple molecules are called monomers and the large complex molecules formed as a result of polymerisation are called polymers.
(Polymers: poly – many, mer – unit/part)

Based on the method of polymerisation, polymers are classified into addition polymers and condensation polymers.

Addition polymers
Addition polymers are obtained by the repeated addition reaction of monomers.

METHANOL (CH3 – OH)
Methanol or methyl alcohol is the first member of the alcohol family.

ETHANOL (CH₃ – CH₂ – OH)
Ethanol or ethyl alcohol is another industrially important alcohol.
Industrial preparation of ethanol
Ethanol is manufactured by the fermentation of molasses. During the production of sugar from sugarcane, a viscous concentrated sugar solution is left behind after the separation of sugar crystals.
This solution is called molasses.
The fermentation is carried out by adding yeast to the dilute molasses. The enzyme invertase present in yeast converts sugar solution to glucose and fructose. Then another enzyme zymase, converts glucose and fructose into ethanol.

• 8 – 10% ethanol thus obtained is known as ‘wash’.
• When wash is subjected to fractional distillation, 95.6% of ethanol is obtained. This is known as rectified spirit.
• 100% of ethanol is known as absolute alcohol.
• Power alcohol is a mixture of 20% absolute alcohol and 80% of petrol. It is used as fuel in vehicles.

Ethanol is an organic compound used in the manufacture of various other organic compounds. In such situations, toxic substances like methanol/pyridine/rubber distillate etc. are added to ethanol in order to prevent its misuse as a beverage. Ethanol thus obtained is called denatured spirit.
When denaturing is done with methanol, the resulting ethanol is called methylated spirit.

• As a solvent for medicines.
• Manufacture of paints.
• As preservatives.
• Production of organic compounds.

ETHANOIC ACID (CH₃ – COOH)
Ethanoic acid (acetic acid) is a carboxylic acid having great industrial importance.
