324452 Assertion :
Alpha ( \(\alpha\) )-amino acids exist as internal salt in solution as they have amino and carboxylic acid groups in near vicinity.
Reason :
\(\mathrm{H}^{+}\)ion given by carboxylic group \((-\mathrm{COOH})\) is captured by amino group \(\left(-\mathrm{NH}_{2}\right)\) having lone pair of electrons.
