The hydridization state of carbon atoms in the product formed by the reaction of ethyl chloride with aqueous $\mathrm{KOH}$ is:
1 $\mathrm{sp}$
2 $5 \mathrm{p}^2$
3 $\mathrm{sp}^3$
4 $\mathrm{sp}^3 \mathrm{~d}$
Explanation:
: When ethyl chloride react with aqueous $\mathrm{KOH}$ then alcohol is formed. In ethyl alcohol all the four valencies of carbon are single bonded. So, the hybridization of carbon atom in $\mathrm{C}_2 \mathrm{H}_5-\mathrm{OH}$ is $\mathrm{sp}^3$.

During polymerization of acetylene to benzene, the state of hybridization of carbon changes from
1 $\mathrm{sp}^2$ to $\mathrm{sp}$
2 $s p^3$ to $s \mathrm{p}$
3 $\mathrm{sp}$ to $\mathrm{sp}^3$
4 $\mathrm{sp}$ to $\mathrm{sp}^2$
Explanation:
: In acetylene is $\mathrm{C}_2 \mathrm{H}_2$ has triple bond between the two carbon atoms and one hydrogen atom attached to each of the carbon, When acetylene is passed through a red not iron tube to give a benzene. In acetylene hybridisation of carbon is $\mathrm{sp}$ and hybridisation of benzene is $\mathrm{sp}^2$. Therefore, the polymerisation of acetylene to benzene changes hybridisation form $\mathrm{sp}$ to $\mathrm{sp}^2$.
