Vedclass · Answer

(B) The molecular formula $C_5H_{10}$ corresponds to a degree of unsaturation (double bond equivalent) of $1$. For cyclic isomers,the possible structures are: $1$. Cyclopentane $2$. Methylcyclobutane $3$. Ethylcyclopropane $4$. $1,1$-Dimethylcyclopropane $5$. $1,2$-Dimethylcyclopropane (cis and trans are stereoisomers,so we count this as one structural isomer) Thus,there are $5$ structural cyclic isomers.

What is the total number of cyclic isomers (excluding stereoisomers) for the molecular formula $C_5H_{10}$?
