The shortest $\mathbf{C}-\mathrm{C}$ bond distance is found in
1 Diamond
2 Ethane
3 Benzene
4 Acetylene
Explanation:
: The distance between them shortens and bond length decreases. In acetylene has a triple bond between two adjacent carbon atoms and the bond length is even shorter. It is close to $120 \mathrm{pm}$. In diamond carbon atom is surrounded by four other carbon atoms and connected to them by strong single covalent bond Hence, the strongest type of chemical bond and bond length is $154 \mathrm{pm}$.

When $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CHCl}_2$ is treated with $\mathrm{NaNH}_2$, the product formed is
1 $\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}_2$
2 $\mathrm{CH}_3-\mathrm{C} \equiv \mathrm{CH}$

In the commercial gasolines, the type of hydrocarbons which are more desirable is
1 Linear unsaturated hydrocarbon
2 Toluene
3 Branched hydrocarbon
4 Straight-chain hydrocarbon
Explanation:
: The knocking property of engine related to with the nature of fuel. The branched hydrocarbons have more desirable. Branching increases the octane number of a fuel. Octane number of means better fuel. So, branched chain hydrocarbons have less knocking and more desirable.

Liquid hydrocarbons can be converted to a mixture of gaseous hydrocarbons by
1 Oxidation
2 Cracking
3 Distillation under reduced pressure
4 Hydrolysis
Explanation:
: Liquid hydrocarbons can be converted to a mixture of gaseous hydrocarbons by cracking. On cracking or pyralysis, the hydrocarbon with higher molecular mass gives a mixture of hydrocarbon having lower molecular mass. Lower hydrocarbon exists in a gaseous state while higher ones are in liquid state or solid state.
