2,6 - dimethyl 4-amino Benzoic acid is more acidic .
due to ortho effect it is more acidic.
ortho effect means:if any group present on ortho position of benzoic acid it always increases acidic nature of acid because this group decreases outer resonance of ring towards acid which increases acidic nature for example orthonitrobenzoic acid is most acidic in any nitro derivative of benzoic acid.orthomethyl benzoic acid is maximum acidic than other isomers.similarly if any group present on ortho position of aniline it decreases basic nature.
