    Due to ortho effect (presence of substituents at ortho position), basicity of aniline decreases. So order should be 1>2>4>3...but ortho hydroxy aniline is more basic than aniline due to intramolecular hydrogen bonding between OH and anilinium ion. ... Now in between 3 and 4 ...4th is more basic than 3rd as there is +R effect of Och3 group and +H effect of ch3 group... +R effect is more dominant over +H effect... so overall order becomes 2>1>4>3
