Chloroxylenol: This compound is a chlorinated derivative of phenol. It is commonly used as a disinfectant and antiseptic. The structure of chloroxylenol has a benzene ring with a hydroxyl group (-OH) and a chlorine atom (Cl) attached to it. In option (a), we can see a phenol ring with a chlorine atom attached to the ring at position 4 and a methyl group attached to position 2, which matches the structure of chloroxylenol.
Terpineol: Terpineol is a monoterpene alcohol found in many essential oils. It has a hydroxyl group (-OH) attached to a six-membered cyclohexene ring. The structure in option (c) corresponds to terpineol, as it is a six-membered ring with a hydroxyl group and two methyl groups, which is characteristic of terpineol. Thus, the correct answer is (D), which corresponds to structures (a) and (c).
Both are constituents of Dettol, where chloroxylenol is a primary active ingredient and terpineol is used for its fragrance and mild antiseptic properties.
Therefore, the correct answer is (D), which includes structures (a) and (c).
