Question

Quizplus · Accepted Answer

Dimethylcyclopropane has the molecular formula C5H10 and consists of a cyclopropane ring with two methyl groups attached to it. Each of the three carbons in the cyclopropane ring can be bonded to one of the methyl groups, resulting in eight possible isomers. However, two of these isomers are identical and cannot be distinguished from one another by any physical or chemical means. Therefore, there are only four distinct dimethylcyclopropanes.
