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 .

Options

A. If both assertion and Reason are true and the Reason is the correct explanation of the assertion.
B. If both assertion and Reason are true but the reason is not the correct explanation of the assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

B

Explanation

p-dichlorobenzene is more symmetrical than o-isomer, so fits closely in the crystal lattice and hence, greater amount of energy is needed to break the crystal lattice. Thus. P-isomers less soluble than o-isomer.
