Which type of isomerism is shown by 1, 2-dimethylcyclopropane?

Question

Which type of isomerism is shown by 1, 2-dimethylcyclopropane? (A) Geometrical isomerism (B) Optical isomerism (C) Position isomerism (D) Conformational isomerism

Tardigrade Admin · Accepted Answer

Cyclic compounds such as 1,2-dimethylcyclopropane exhibit cis-trans isomerism. In the cis-isomer, both the methyl groups are situated on the same side (either above or below the place of the ring) and in trans-isomer, the methyl groups are on opposite sides.
