Q. No.
Consider the given two statements:
Assertion (A): p-Toluidine is a stronger base than m-toluidine.
Reason (R): The methyl group from m-position exerts a smaller electron-donating inductive (+l) effect than from p-position.
Options:
1. Both (A) and (R) are True and (R) is the correct explanation for (A).
2. Both (A) and (R) are True but (R) is not the correct explanation for (A).
3. (A) is True but (R) is False.
4. Both (A) and (R) are False.
