Why is para-aminobenzoic acid more acidic than ortho-aminobenzoic acid?
Compare the acidic strength of o-, m-, p-aminobenzoic acids.
I got that meta will be the most acidic as it won't be able to show R+ effect of $\ce{NH2}.$
But among the other two, i.e. ortho and para, ...

Basicity comparison between pyridine amines and other compounds
In cases 1, 2, 3, the compounds will resonate, thus giving them more stability.
Firstly, I want to know whether nitrogen has a +M effect? (due to it having a lone pair of electrons?)
In case 1, ...
