The order of increasing basic strength among m-toluidine (I), p-toluidine (II) and o-toluidine (III) is

Answer»

`III lt II lt I`
`II lt III lt I`
`III lt I lt II`
`II lt I lt III`.

Solution :p-Toluidine `(K_(b) =12 xx 10^(-10))`
m-Toluidine `(K_(b)= 5 xx 10^(-10))`
o-Toluidine `(K_(b) = 2.6 xx 10^(-10))`
`:.` Correct order is
`III lt I lt II`
