| Directions : (1 - 15) |
| For question numbers 1-15, a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. |
| Assertion: p-Dichlorobenzene is less soluble in organic solvents than the corresponding o-isomer. |
| Reason: o-Dichlorobenzene is polar while p-dichlorobenzene is not. |
A) Assertion and reason both are correct statements and reason is correct explanation for assertion.
B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C) Assertion is correct statement but reason is wrong statement.
D) Assertion is wrong statement but reason is correct statement.
Correct Answer: B
Solution :
p-Dichlorobenzene being more symmetrical than o-isomer fits closely in the crystal lattice and hence greater amount of energy is needed to break the crystal lattice. Thus, p-isomer is less soluble than o-isomer.
