(B) The molecular formula $C_5H_8$ corresponds to the general formula $C_nH_{2n-2}$,which indicates the presence of one triple bond (alkyne) or two double bonds (alkadiene). For $C_5H_8$ with one triple bond,the possible structural isomers are: $1$. $CH_3-CH_2-CH_2-C \equiv CH$ (Pent$-1-$yne) $2$. $CH_3-CH_2-C \equiv C-CH_3$ (Pent$-2-$yne) $3$. $CH_3-CH(CH_3)-C \equiv CH$ ($3$-Methylbut$-1-$yne) Thus,there are $3$ possible structures.

How many structures are possible for $C_5H_8$ with one triple bond?
