A)
B)
C)
D)
Correct Answer: B
Solution :
The group showing electron-donating field effect (such as\[-N{{H}_{2}},-OH\]) should stabilize the inter- mediate ions, i.e., makes the ring more reactive towards electrophilic substitution than benzene and are called activating group, while electron- withdrawing group (such as -CI,\[N{{O}_{2}}\]) increases the positive charge on ring, thus deactivates the ring. Hence, phenol is more readily attacked by an electrophile.
