Which of the following will be optically active?
Options:
Answer:
A
Solution:
(A) trans-1,2-Dimethylcyclobutane : two stereocentres, no plane or centre of symmetry - chiral, so a pure sample is optically active.
(B) cis-1,2-Dimethylcyclobutane has an internal mirror plane (meso) - inactive.
(C) 1,1-Dimethylcyclobutane has no stereocentre - inactive.
(D) trans-1,3-Dibromocyclobutane has a plane of symmetry through C1 and C3 - inactive.
