Which of the following group is sharp ortho and para directive?
Options
- A- C ₆ H ₅
- B- OH
- CCH ₃
- D- Cl
Correct answer
B. - OH
Step-by-step 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.
