| B. | Wood Spirit | II. | Diethyl ether |
| C. | Anaesthetic | III. | Methanol |
| D. | Acetylsalicylic Acid | IV. | Phenol |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-IV, B-III, C-II, D-I
Many alcohols, phenols and ethers are better known by their common names, which often come from their source or use:
(A) Carbolic acid — This matches (IV) Phenol. Phenol, \( \ce{C6H5OH} \), was first obtained from coal tar and is weakly acidic, hence the name carbolic acid. It is used as an antiseptic.
(B) Wood Spirit — This matches (III) Methanol. Methanol, \( \ce{CH3OH} \), was once made by the destructive distillation of wood. It is poisonous; small amounts cause blindness.
(C) Anaesthetic — This matches (II) Diethyl ether. Diethyl ether, \( \ce{C2H5OC2H5} \), was widely used as a general anaesthetic in surgery.
(D) Acetylsalicylic Acid — This matches (I) Aspirin. Aspirin is made by acetylation of salicylic acid (2-hydroxybenzoic acid) and is used as an analgesic and antipyretic.
Shortcut: The pair A–IV appears only in Option (2).
