Strength of acid increases with the attachment of group showing –I effect and decreases with the attachment of group showing +I effect. Which of the following is correct sequence of basic strength in aqueous solution ?
(a) CH3NH2 < (CH3)2NH < (CH3)3N
(b) (CH3)2NH < CH3NH2 < (CH3)3N
(c) (CH3)3N < (CH3)2NH < CH3NH2
(d) (CH3)3N < CH3NH2 < (CH3)2NH
Correct Option (d) (CH3)3N < CH3NH2 < (CH3)2NH
Explanation :
Such order of basic strength is weighted result of these three factors
(a) Inductive effect
(b) Solvation effect
(c) Steric hindrance
