Question: Four species are listed below:

(i) $H C {O^{-}}_{3}$

(ii) $H_{3} O^{+}$

(iii) $H S {O^{-}}_{4}$

(iv) $H S O_{3} F$

Which one of the following is the correct sequence of their acid strength-

Options:

A) iv <ii <iii <i

B) ii <iii <i <iv

C) i <iii <ii <iv

D) iii <i <iv <ii

Show Answer

Answer:

Correct Answer: C

Solution:

The $p K_{a}$ values of $H C O_{3}^{-}$ and $H S O_{4}^{-}$ are 10.25,-1.74 and 1.92 respectively and $H S O_{3}$ F is super acid. $(i v) > (i i) >$ (iii)>(i)
