Assertion: p-Dichlorobenzene is less sol...

Assertion: p-Dichlorobenzene is less soluble in organic solvents than the corresponding o-isomer
Reason o-Dichlorobenzene is polar while p-dichlorobenzene is non-polar .

A

If both assertionn and reason are true, and reason is the true explanation of the assertion.

B

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

C

If assertion is true, but reason is false.

D

If both assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
Correct explanation. Being symmetrical, p-dichlorobenzene molecules fit closely in the crystal lattice and hence has stronger intermolecular forces of attraction than those of o-dichlorobenzene. As a result, large amount of energy is needed to dissolve p- than o-isomer.
