Question

A compound having the formula $N{H}_{2}C{H}_{2}COOH$ will behave

• A. only as acid
• B. only as base
• C. both acid and base
• D. neither acid nor base
  
  

Answer 1

The correct option is C both acid and base

Explanation :

Glycine will behave both as an acid and base (amphoteric).
In aqueous state, glycine exists in zwitter ion form wherein the $H^{+}$ from the acid $-COOH$ part migrates to the amine part $-N{H}_2$
Thus they are amphoteric in nature.
