Vedclass · Answer

(B) For the molecular formula $C_5H_8$,the degree of unsaturation is $2$. Since we are looking for alkynes,each structure must contain one triple bond.The possible structural isomers are:$1.$ $CH \equiv C-CH_2-CH_2-CH_3$ ($1$-pentyne)$2.$ $CH_3-C \equiv C-CH_2-CH_3$ ($2$-pentyne)$3.$ $CH \equiv C-CH(CH_3)_2$ ($3$-methyl-$1$-butyne)Therefore,there are $3$ possible structural alkynes.

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