Question

Out of benzene and phenol, phenol is more easily nitrated because

• A. presence of $—OH$ group in phenol increases the electron density at $ortho$ and $para$-position
• B. presence of $—OH$ group in phenol decreases the electron density at $ortho$ and $para$-position
• C. nitration being electrophilic substitution requires less density at $ortho$ and $para$-position
• D. phenol is more reactive than benzene due to $-R$ effect

Answer 1

Answer: (A)

Phenol is more easily nitrated than benzene as the presence of $—OH$ group in phenol increases the electron density at $ortho$ and para-positions in benzene ring by $+R$ effect.
