317191 Assertion :
Toluene is o , p-directing.
Reason :
The hyperconjugation effect of the methyl group increases the electron density at o - and p-positions in the benzene ring.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
