(B) The molecular formula $C_5H_8$ corresponds to the general formula $C_nH_{2n-2}$,which indicates an alkyne. The possible structural isomers for $C_5H_8$ are: $1$. $Pent-1-yne$ $(CH_3-CH_2-CH_2-C \equiv CH)$ $2$. $Pent-2-yne$ $(CH_3-CH_2-C \equiv C-CH_3)$ $3$. $3-Methylbut-1-yne$ $(CH_3-CH(CH_3)-C \equiv CH)$ Thus,there are $3$ possible alkynes.

The number of possible alkynes with the molecular formula $C_5H_8$ is
