Assertion : Glycine is amphoteric in nature .
Reason: Glycine contain both acid and basis 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
Glycine is an amino acid, it contains both `NH_2` as well as –COOH groups and therefore, its aqueous solution form Zwitter ion which is amphoteric in nature.
`underset("Glycine")(NH_2 CH_2 COOH)" "underset("Zwitter ion")(NH_3^+ CH_2 COO^-)`
Therefore, both assertion and reason are true.
