Question

Quizplus · Accepted Answer

1,2-dimethylcyclobutane has two different substituents (methyl groups) attached to adjacent carbons in a cyclic structure, allowing for the possibility of cis-trans isomers. 1,1-dimethylcyclobutane has both methyl groups attached to the same carbon, making cis-trans isomers impossible.
