Arrange the following bases in order of ...

Arrange the following bases in order of decreasing basicity:
`S^(2-),CH_(3)COO^(Θ), CH^(Θ), NH_(3),F^(Θ)`

Text Solution

Verified by Experts

Stronger the acid, weaker is conjugate base and vice versa. First arrange them in decreasing acidic character.
`HF gt CH_(3) COOH gt NH_(4)^(o+) gt HCN gt HS^(Θ)`
Therefore, the decreasing order of basic character.
`S^(2-) gt CN^(Θ) gt NH_(3) gt CHCOO^(Θ) gt F^(Θ)`
