Question

Match the pairs
Group ‘A’
a. C₂H₆b. C₂H₂c. CH₄Od. C₃H₆

Group ‘B’
1. Unsaturated hydrocarbon
2. Molecular formula of an alcohol
3. Saturated hydrocarbon
4. Triple bond

Answer 1

Answer:

1.unsaturated hydocarbon=c3H6

2.molecular formula of an alcohol=CH4O

3.saturated hydrocarbon=c2H6

4.triple bond=C2H2

Answer 2

Answer:

(a) C2H6 - 3. Saturated hydrocarbon

Alkanes are acyclic saturated hydrocarbon as all the carbon atoms are singly bonded with hydrogen atoms. Alkanes are also called paraffin.

(b) C2H2 - 4. Triple bond

Alkynes are unsaturated hydrocarbons where at least carbon atom is tripled bonded with another carbon atom. Alkynes are also called acetylenes.

(c) CH4O - 2. Molecular formula of a alcohol

Alcohols are organic compounds in which a carbon atom is bonded with the hydroxyl group. Ethanol is the most common alcohol.

(d) C3H6 - 1. Unsaturated hydrocarbon

Alkenes are unsaturated hydrocarbons in which at least one carbon atom is double-bonded with another carbon atom. The simplest alkene is ethene.
