To prepare quaternary ammonium compounds...

To prepare quaternary ammonium compounds we heat _____ with a large excess of alky1 halide .

A

ammonia

B

primary amine

C

secondary amine

D

any of these

Text Solution

Verified by Experts

The correct Answer is:
D
`NH_(3)+4RXoverset(Delta)rarrR_(4)overset(+)NX+ 3HX`
`RNH_(2)+3RXoverset(Delta)rarrR_(4)overset(+)NX+2HX`
`R_(2)NH+2RXoverset(Delta)rarrR_(4)overset(+)NX+HX`
We can also use a tertiary amine to yield a quaternary compound For example ethyltrimethylammonium iodide can be prepared by heating trimethylamine with ethy1 iodide
`(CH_(3))_(3)N+C_(2)H_(5)I overset(Delta)rarr(CH_(3))_(3)overset(+)NC_(2)H_(5)Ibar` .
