Suitable explanation for the order of basic character (CH3)3N

Question

Suitable explanation for the order of basic character (CH3)3N < (CH3)2NH is (A) steric hinderance by bulky methyl group (B) higher volatility of 3° amine (C) decreased capacity of H-bond formation withH2O (D) decreased electron density at N-atom

Tardigrade Admin · Accepted Answer

( CH 3)3 N is less basic due to steric hindrance by bulky methyl group prevent any acid to take a lone pair of nitrogen.

Q. Suitable explanation for the order of basic character $(C H_{3})_{3} N < (C H_{3})_{2} N H$ is

steric hinderance by bulky methyl group

higher volatility of 3 $^{\circ}$ amine

decreased capacity of H-bond formation with $H_{2} O$

decreased electron density at N-atom

$(C H_{3})_{3} N$ is less basic due to steric hindrance by bulky methyl group prevent any acid to take a lone pair of nitrogen.

Q. Suitable explanation for the order of basic character (CH3​)3​N<(CH3​)2​NH is

steric hinderance by bulky methyl group

higher volatility of 3∘ amine

decreased capacity of H-bond formation withH2​O

decreased electron density at N-atom

(CH3​)3​N is less basic due to steric hindrance by bulky methyl group prevent any acid to take a lone pair of nitrogen.
