q)which is more basic aniline or ortho methoxy benzene?is there ortho effect?

Hello dear somesh

Ortho effect is only shown by two compound Benzoic acid or ANILINE

But in case of solving problem like comparing acidic and basic strength ..we consider this effect only when all compound are either aniline or benzoic ..

Example : (if u r unable to understand above lines )

A   ( ortho-methyl aniline )

B  ( para methyle aniline )

C ( meta methyl aniline)

Then all compound are aniline ...so ortho effect is to be considered ...and

A ( ortho methyl aninline )

B ( methyl benzene)

Here two compound become different...so we don't consider ortho effect here.....when the two compound which are considered as ....are aniline..then only look for ortho effect ..

This is so far detail of ortho effect.....now as per question

Basic strength of  Aniline is more than that of ortho methoxy benzene  because aniline as N as donar atom (lone pair) and methoxy has O as donar atom...and tendency to donate electron is more for N than for O ...so electron density in aniline will be more as compared to ortho methoxy benzene.....

So aniline is more basic in nature

I hope it is clear now ..both ortho effect n aniline
