Acetalehyde is used:
(A) As antiseptic inhalent
(B) In the preparation of a hypnotic
(C) In the preparation of solid fuel
(D) In the preparation of unbreakable glass
Options
- AA, B, C only
- BB, C, D only
- CA, C, D only
- DAll A, B, C, D
Correct answer
A. A, B, C only
Step-by-step solution
Let's check the uses of acetaldehyde ((\mathrm{CH}_3 \mathrm{CHO})):
1. As antiseptic inhalent (\rightarrow(\mathrm{A}): \quad) Yes. Acetaldehyde is sometimes used in medicine (though limited now).
2. In the preparation of a hypnotic (\rightarrow(\mathrm{B}): \quad) Yes. Acetaldehyde is used in making chloral hydrate, which is a sedative/hypnotic drug.
3. In the preparation of solid fuel (\rightarrow(\mathrm{C}): \quad) Yes. Acetaldehyde is used in preparing paraldehyde and metaldehyde, both of which are solid fuels.
4. In the preparation of unbreakable glass (\rightarrow(\mathrm{D}): \quad) Yes. Acetaldehyde is used in making acetal resin, which is a component of safety/unbreakable glass.
So all four options are correct.
