Hyperconjugation effect

Vedclass · Answer

(D) Step $1$: The basic strength of alkylamines in the aqueous phase depends on three main factors: inductive effect, solvation effect, and steric hindrance.Step $2$: The inductive effect ($+I$ effect) increases the electron density on the nitrogen atom, making it more basic.Step $3$: The solvation effect (stabilization of the conjugate acid by hydrogen bonding with water) stabilizes the cation; more substituted amines have less hydrogen bonding.Step $4$: Steric hindrance (crowding around the nitrogen atom) hinders the approach of the proton.Step $5$: Hyperconjugation effect does not play a significant role in determining the basicity of alkylamines in the aqueous phase. Therefore, the correct option is $D$.

The basic strength of alkylamines in the aqueous phase is not decided by . . . . . . .
