Vedclass · Answer

(D) The chemical formula of naphthalene is $C_{10}H_8$.In the structure of naphthalene,there are two fused benzene rings.The number of $\pi$-bonds is equal to the number of double bonds in the structure,which is $5$.The number of $\sigma$-bonds can be calculated by counting all single bonds and one bond from each double bond.Total $\sigma$-bonds = $19$.Therefore,the number of $\pi$-bonds and $\sigma$-bonds are $5$ and $19$ respectively.The correct option is $(D)$.

The number of $\pi$-bonds and $\sigma$-bonds present in naphthalene are respectively
