Amines Ques 23
23. The correct order of the basic strength of methyl substituted amines in aqueous solution is :
[2019]
(a) $(CH_3)_2 NH>CH_3 NH_2>(CH_3)_3 N$
(b) $(CH_3)_3 N>CH_3 NH_2>(CH_3)_2 NH$
(c) $(CH_3)_3 N>(CH_3)_2 NH>CH_3 NH_2$
(d) $CH_3 NH_2>(CH_3)_2 NH>(CH_3)_3 N$
Show Answer
Answer:
Correct Answer: 23.(a)
Solution:
(a) Account for the inductive effect, solvation effect (H-bonding.) and steric hinderance for basic character in aqueous solutions
$\hspace{20mm}(CH_3)_2 NH>CH_3 NH_2 > (CH_3)_3 N $
