Order of the basic strength of the following compounds is

Answer

C

Explanation

the conjugate acids of the given bases are `CH_(3)COOH,CH_(3)CH_(2)CH_(2)CH_(3),NH_(3) and C_(6)H_(5)OH`. Their acid strengths decrease in the order:
`CH_(3)COOH gt C_(6)H_(5)OH gt NH_(3) gt CH_(3) CH_(2) CH_(2) CH_(3)`.
therefore, their basic strengths decrease in the reverse order:
`CH_(3)CH_(2)CH_(2)CH_(2)^(-)`
(ii) `gtNH_(2)^(-)`
(iii) `gt C_(6)H_(5)O^(-)`
(iv) `gt CH_(3)COO^(-)`
(i), i.e., option (c) is correct.
