Question

A compound undergoes the following reactions: (i) With saturated NaHSO3, it gives a white precipitate. (ii) On reduction, it gives a secondary alcohol. (iii) With I2 sodium carbonate, it gives iodoform. The compound is: (A) acetaldehyde (B) acetamide (C) acetone (D) ethylene dibromide

Tardigrade Admin · Accepted Answer

Acetone gives all the three reactions. It gives addition compound with sodium bisulphite and on reduction, it gives secondary propyl alcohol. With I2 and Na2CO3, it gives yellow precipitate of iodoform. (Haloform reaction).

Q. A compound undergoes the following reactions: (i) With saturated $N a H S O_{3},$ it gives a white precipitate. (ii) On reduction, it gives a secondary alcohol. (iii) With $I_{2}$ sodium carbonate, it gives iodoform. The compound is:

acetaldehyde

acetamide

acetone

ethylene dibromide

Acetone gives all the three reactions. It gives addition compound with sodium bisulphite and on reduction, it gives secondary propyl alcohol. With $I_{2}$ and $N a_{2} C O_{3},$ it gives yellow precipitate of iodoform. (Haloform reaction).
