Which of the following group is sharp ortho and para directive?
- A \(-\mathrm{C}_{6} \mathrm{H}_{5}\)
- B \(-\mathrm{OH}\)
- C \(\mathrm{CH}_{3}\)
- D \(-\mathrm{Cl}\)
Answer & Solution
Correct Answer
(B) \(-\mathrm{OH}\)
Step-by-step Solution
Detailed explanation
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.
-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.
