(A) The molecular formula $C_5H_{10}$ corresponds to a degree of unsaturation of $1$. This allows for either one double bond or one ring. Structural isomers with one double bond (alkenes): $1$. $CH_3-CH_2-CH_2-CH=CH_2$ (pent$-1-$ene) $2$. $CH_3-CH_2-CH=CH-CH_3$ (pent$-2-$ene) $3$. $CH_2=C(CH_3)-CH_2-CH_3$ ($2-$methylbut$-1-$ene) $4$. $CH_3-CH=C(CH_3)-CH_3$ ($2-$methylbut$-2-$ene) $5$. $CH_2=CH-CH(CH_3)_2$ ($3-$methylbut$-1-$ene) Structural isomers with one ring (cycloalkanes): $6$. Cyclopentane $7$. Methylcyclobutane $8$. $1,1-$Dimethylcyclopropane $9$. $1,2-$Dimethylcyclopropane (cis and trans are stereoisomers,but structural isomers include $1,1-$ and $1,2-$) $10$. Ethylcyclopropane Total structural isomers = $10$.

The total number of structural isomers for the molecular formula $C_5H_{10}$ (including cyclic and acyclic isomers) is:
