Question

Which one of the following is not acid-base conjugate pair? (A)  HONO, NO2-  (B) CH3NH3+,CH3NH2  (C)  C6H5COOH,C6H5COO- (D)  H3O+,OH-

Two substance that differ from each other only by one proton are refered to as conjugate acid-base pair. except option 'c' all pairs are differ from each other only by one proton and hence they are conjugate acid-base pair. hence H 3 O +, OH -are not conjugate acid-base pair.

Q. Which one of the following is not acid-base conjugate pair?

$H ONO, N O_{2}^{-}$

$C H_{3} N H_{3}^{+}, C H_{3} N H_{2}$

$C_{6} H_{5} COO H, C_{6} H_{5} CO O^{-}$

$H_{3} O^{+}, O H^{-}$
