Which of the following compounds will have the highest melting point here?

Options

AIII
BII
CI
DThey have equal melting point

Correct answer

B. II

Step-by-step solution

Compound II is most symmetrical because it has both C H 3 groups and Br atoms are apposite to each other therefore, it fits in the crystal lattice better than the other two isomers and hence it has high melting point.
