p-toluidine is more basic because -CH3 is +M which decrease the acidic character but in case of meta toluidine +M is not applicableas +I is applicable as it is distance effect & applicabe in both para & meta
p-toluidene is more basic than m-toluidene because in p-toluidene hyperconjugation effect of CH3 is available, whereas in m-toluidene hyperconjugation effect is not present because hyperconjugation does not acts at meta position
