Solution
The correct option is B
Ethane, Ethylchloride & CH3−CH2−OH When alkane undergoes halogenation alkyl halide is formed. When alkyl halide reacts with aqueous KOH, it undergoes sunstitution reaction to form alcohol. When alcohol undergoes oxidation, aldehyde is formed. Hence, the correct answer is option (b).
