In the reaction, \(\text { 2nR }-\mathrm{X} \xrightarrow[\text { Dryether }]{+2 \mathrm{nNa}} \text { product }\) The product obtained is
1 2 n-alkene
2 n-sodium halide
3 n-alcohol
4 n-alkane
Explanation:
When alkyl halide react with sodium metal in the presence of dry ether to form a alkane this reaction is known as Wurtz reaction.

The number of alkenyl groups possible from $\mathrm{C}_4 \mathrm{H}_7$ are
1 7
2 5
3 3
4 8
Explanation:
: In $\mathrm{C}_4 \mathrm{H}_7$ the possible number of alkenyl group are - (i) $\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}=\mathrm{CH}-$ (ii) $\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_2-$ (iii) $\mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}_2-\mathrm{CH}_2$ (iv) (v) So, the no. of alkenyl group in $\mathrm{C}_4 \mathrm{H}_7$ is 5 .

The compound with highest boiling point
1 n-hexane
2 n-pentane
3 2,2-dimethylpropane
4 2-methylbutane
Explanation:
: Boiling point $\propto$ molecular mass $\propto \frac{1}{\text { branching }}$ ( $\because$ Surface area decreases) $\therefore$ n-hexane has the highest boiling point among the given.
