Which of the following base is weakest

Answer»

`NH_(4)OH : K_(b) = 1.6 xx 10^(-6)`
`C_(6)H_(5)NH_(2) : K_(b) = 3.8 xx 10^(-10)`
`C_(2)H_(5)NH_(2) : K_(b) = 5.6 xx 10^(-4)`
`C_(6)H_(7)N : K_(b) = 6.3 xx 10^(-10)`

Solution :Smallest value of `K_(b)` indicates that aniline `(C_(2)H_(5)NH_(2))` is the WEAKEST BASE.
