Which of the following group is sharp ortho and para directive?

A$$-C_{6}H_{5}$$
B$$-OH$$
Correct Answer
C$$-CH_{3}$$
D$$-Cl$$

Solution

All the groups are $$o-$$ and p-directive. But in $$-OH$$ group, lone pair of electron present at o-atom increases electron density for electrophile at o- and p-positions. Thus, it is sharp o- and p- directive.
