Assertion: Melting points of isomeric dihalobenzenes are nearly the same.
Reason: Isomeric dihalobenzenes have different molecular masses.

A

If both assertion and reason are true and reason Is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assetion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
The para-isomers are high melting as compared to their ortho-and meta-isomers. This is due to symmetry of para -isomers that fit in crystal lattice better as compared to ortho-and meta-isomers.
