Chemistry Question on Acids and Bases
Given below are two statements : one is labelled as Assertion (A) and the other is labelled asReason (R)
Assertion (A): α-halocarboxylic acid on reaction with dil NH3 gives good yield of α-aminocarboxylic 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 :
Both (A) and (R) are correct and (R) is the correct explanation of (A)
(A) is not correct but (R) is correct
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
(A) is correct but (R) is not correct
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
Solution
Correct answer is (a) Both (A) and (R) are correct and (R) is not correct explanation of (A)
Assertion (A): α-halocarboxylic acid on reaction with dil NH3 gives good yield of α-aminocarboxylic acid whereas the yield of amines is very low when prepared from alkyl halides (correct)
Reason (R): Amino acids exist in zwitter ion form in aqueous medium (True but not correct explanation)
