More the acidic character less would be the value of pKa value.

Q. Determine the order of pKa values for given acids:
(a) $C H_{3} - COO H$
(b) $O_{2} N - C H_{2} - COO H$
(c) $NC - C H_{2} - COO H$
(d) $M e O - C H_{2} - COO H$

b>a>c>d

a>d>c>b

a>d>b>c

b>c>d>a

More the acidic character less would be the value of pK_a value.
