Q. Alanine, the amino acid the respective structure at $pH =2$ and $pH =10$ will be
Amines
A
$NH_2 - \overset{\underset{|}{C}H_3}{CH} - COO^-$, $ H_3\overset{+}{N} - \overset{\underset{|}{C}H_3}{CH} - COOH$
B
$H_3\overset{+}{N} - \overset{\underset{|}{C}H_3}{CH} - COO, H_3\overset{+}{N}- \overset{\underset{|}{C}H_3}{CH} - COOH$
C
$H_3\overset{+}{N} - \overset{\underset{|}{C}H_3}{CH} - COOH, NH_2- \overset{\underset{|}{C}H_3}{CH} - COO^{\ominus}$
D
$NH_2- \overset{\underset{|}{C}H_3}{CH} - COO^{-}, H_3\overset{+}{N} - \overset{\underset{|}{C}H_3}{CH} - COO$
Solution:
At $P_H = 2 : H_3N^+ - \overset{\underset{|}{C}H_3}{CH} - COOH$
At $P_H = 10 : NH_2 - \overset{\underset{|}{C}H_3}{CH} - COO^-$
