(i) \[HC{{O}^{-}}_{3}\] |
(ii) \[{{H}_{3}}{{O}^{+}}\] |
(iii) \[HS{{O}^{-}}_{4}\] |
(iv) \[HS{{O}_{3}}F\] |
Which one of the following is the correct sequence of their acid strength? |
A) iv <ii <iii <i
B) ii <iii <i <iv
C) i <iii <ii <iv
D) iii <i <iv <ii
Correct Answer: C
Solution :
[c] The \[p{{K}_{a}}\]values of \[HC{{O}_{3}}^{-}\]and \[HS{{O}_{4}}^{-}\]are 10.25,-1.74 and 1.92 respectively and \[HS{{O}_{3}}\]F is super acid. \[(iv)>(ii)>\](iii)>(i)You need to login to perform this action.
