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 bring electrophilic substitution requires less density at ortho and para positon.
• D. Phenol is more reactive than benzene due to –R effect

Answer 1

Answer: (A)

Presence of $- OH$ group in phenol increases the electron density at ortho and para-position

Answer 2

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