Assertion: All amino acids exists as Zwitter ions.
Reason: Amino acids have both `- NH_(2)` and `-COOH` group

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
All amino acids possess amino as well as carboxylic group. –`NH_2` group is basic while –COOH group is acidic. Therefore, they behave as zwitter ion (dipolar ion). Here, both assertion and reason are true and reason is a correct explanation.
