Moderate

A

$C_{2} H_{6}$
B

$C_{2} H_{4}$
C

${CH}_{4}$
D

$C_{2} H_{2}$

Solution

[Step 1]:
Strength of the carbon-carbon bond increases with increase in number of bonds between carbon and carbon.
[Step 2]:
In option (1) ${CH}_{3} - {CH}_{3}$ number of bonds between carbon and carbon is one.
[Step 3]:
In option (2) $C H_{2} = C H_{2}$ number of bonds between carbon and carbon are two.
[Step 4]:
In option (3) $C H_{4}$ there is no carbon-carbon bonds.
[Step 5]:
In option (4) $H C \equiv C H$ number of bonds between carbon and carbon are three.
