Vedclass · Answer

(B) The molecular formula $C_6H_{10}$ corresponds to an alkyne (general formula $C_nH_{2n-2}$). The structural isomers are as follows:$1$. Hex$-1-$yne: $CH_3-CH_2-CH_2-CH_2-C \equiv CH$$2$. Hex$-2-$yne: $CH_3-CH_2-CH_2-C \equiv C-CH_3$$3$. Hex$-3-$yne: $CH_3-CH_2-C \equiv C-CH_2-CH_3$$4$. $3-$Methylpent$-1-$yne: $CH_3-CH_2-CH(CH_3)-C \equiv CH$$5$. $4-$Methylpent$-1-$yne: $CH_3-CH(CH_3)-CH_2-C \equiv CH$$6$. $4-$Methylpent$-2-$yne: $CH_3-CH(CH_3)-C \equiv C-CH_3$$7$. $3,3-$Dimethylbut$-1-$yne: $(CH_3)_3C-C \equiv CH$There are a total of $7$ structural isomers.
