Question

Glycine act as zwitter ion but antranilic acid doesnot exist as zwitter ion why

Answer 1

glycine contain one NH3 ion and COOH ion COOH loose its hydrogen so a proton donor so acid and form COO - VE and NH3 gain proton and form NH4 +ve and if both acidic and basic group are present in same molecule than its a zwitter ion but antranilic acid just has COOH group which is acidic and had no basic ion so not a zwitter ion

hope it helps
