Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): α-halocarboxylic acid on reaction with dil. NH3 gives good yield of α-amino carboxylic acid whereas the yield of amines is very low when prepared from alkyl halides.

Reason (R): Amino acids exist in zwitter ion form in aqueous medium.

In the light of the above statements, choose the correct answer from the options given below :

Options:

Answer:
B
Solution:

.

α-halocarboxylic acid react with dill NH3 at faster than amines and amino acids exist in zwitter ion form in aqueous medium.

So, both (A) and (R) are correct and (R) is the correct explanation of (A).
