Assertion : p-Dichlorobenzene is less so...

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 (A) and (R) are correct and (R) is the correct explanation of (A).

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

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