Question

Amongst the following, the strongest base in aqueous medium is . (A) CH3NH2 (B) NCCH2NH2 (C) (CH3)2NH (D) C6H5NHCH3

Compound		Factors responsible for basic character are
a	$C H_{3} - N H_{2}$	Inductive effect (+I)
b	$NC - C H_{2} - N H_{2}$	Inductive effect (-I)
c	$(C H_{3})_{2} N H$	-I effect and resonance

Since,

+ I

effect and solvation increases basic character but

- I

effect and resonance decreases basic character. Hence, correct choice is (c)
