Which of the following is a characteristic reaction of phenols? (2021) 2021

Step 1: Understand what phenols are. Phenols are organic compounds that contain a hydroxyl group (-OH) attached to a benzene ring.
Step 2: Learn about the hydroxyl group. The hydroxyl group is electron-donating, which means it can increase the electron density of the benzene ring.
Step 3: Know what halogenation is. Halogenation is a chemical reaction where halogens (like chlorine or bromine) are added to a compound.
Step 4: Recognize the effect of the hydroxyl group. Because the hydroxyl group donates electrons, it makes the benzene ring more reactive towards halogens.
Step 5: Conclude that phenols can easily react with halogens. This reaction is a characteristic reaction of phenols.
