cis-1-bromo-3-methylcyclobutane

Options:
Answer:
A
Solution:
cis-1-Bromo-3-methylcyclobutane has a plane of symmetry passing through C1 and C3 (and their substituents Br and CH3), bisecting the ring - the two halves of the ring are mirror images. In trans-1-bromo-3-methylcyclobutane (Br down, CH3 up) no such plane exists, so the trans isomer is chiral and the cis isomer is achiral.
