Amines
Class:XII / Unit:13

1. C₃H₈N can not represent

quartemary ammonium salt
1° ammine
2° ammine
3° ammine

2. The most convenient method to prepare primary (i Amine) amine containing one carbon atom less is

Reduction of isonitriles
Reductive amination of aldehydes
Hofmann bromamide reaction
Gabriel phthalmidie synthesis

3. When excess of ethyl iodide is treated with ammonia, the product is

triethylamine
tetrathylammonium iodide
diethylamine
ethylamine

4. Amides may be converted into amines by a reaction named after

Kekule
Perkin
Hofmann Bromide
Claisen

5. Secondary amines can be prepared by

reduction of nitriles
reduction of isonitriles
oxidation of N-substituted amides
reduction of nitro compounds

6. Which of the following amides will give ethylamine on reaction with sodium hypobromide?

Butanamide
Propanamide
Acetamide
Benzamide

7. Benzoic acid is treated with SOCl₂ and the product (X) formed is reacted with ammonia to give (Y). (Y) on reaction with Br2 and KOH gives (Z). (Z) in the reaction is

benzamide
aniline
benzoyl chloride
chlorobenzene

8. Amine that cannot be prepared by Gabricl-Phthalmidie synthesis is

aniline
benzyl amine
methyl amine
iso-butylamine

9. Tertiary amines have lowest boiling points amongst isomeric amines because

they are more polar in nature
they are most basic in nature
they do not form hydrogen bonds
they have highest molecular mass

10. Electrophilic substitution of aniline with bromine water at room temperature gives

2-bromoaniline
3-bromoaniline
2, 4, 6-tribromoaniline
3, 5, 6-tribromoaniline
