Assertion (A) : In aqueous solution, -amino acids exists as internal salt called as zwitter ion.
Reason (R) : Proline is a natural amino acid having a secondary amino group.
The correct option among the following is
- A (A) is true, (R) is true and (R) is the correct explanation for (A)
- B (A) is true, (R) is true but (R) is not the correct explanation for (A)
- C (A) is true but (R) is false
- D (A) is false but (R) is true
Answer & Solution
Correct Answer
(B) (A) is true, (R) is true but (R) is not the correct explanation for (A)
Step-by-step Solution
Detailed explanation
In aqueous solution, the carboxyl group can lose a proton and amino group can accept a proton, giving rise to a dipolar ion known as zwitter ion. This is neutral but contains both positive and negative charges. In zwitter ionic form, amino acids show amphoteric behaviour as they…
