Decreasing order of basicity is 
(1) $$ CH_3CONH_2$$
(2)$$ CH_{3}CH_{2}NH_2 $$
(3) $$ Ph-CH_{2}CONH_{2} $$

The correct order of increasing basic nature for the bases $$ NH_{3} $$,$$ CH_{3}NH_{2} $$ and $$ (CH_{3})_{2}NH $$ is 

Aniline and methyl amine can be differentiated by 

Among the following, the strongest base is

Azo dye is prepared by the coupling of pehnol and :
