Name the following:
(i) Process by which ethane is obtained from ethene.
(ii) A hydrocarbon which contributes towards the greenhouse effect.
(iii) Distinctive reaction that take place when ethanol is treated with acetic acid.

Solution

(i) Ethene is an unsaturated hydrocarbon whereas ethane is a saturated hydrocarbon.
Reduction of ethene
The reaction can be given as follow:
$C H_{2} = C H_{2} + H_{2} \overset{N i}{\to C H_{3} - C H_{3}}$
(ii) A hydrocarbon that contributes to the greenhouse effect is Methane.
(iii) Reaction that takes place when ethanol is treated with acetic acid is an esterification reaction.
Esterification reaction- Esterification is the process of combining an organic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and water.
