Why does an alkyl group increase the basic strength of an amine?
AIt pushes electrons to nitrogen
BIt pulls electrons from nitrogen
CIt blocks electrons at nitrogen
DIt stores electrons near nitrogen
Answer & Solution
Correct answer: A. It pushes electrons to nitrogen
1. Basicity depends on how available the nitrogen lone pair is.
2. An alkyl group is electron releasing.
3. It pushes electrons towards nitrogen and makes the unshared pair more available.
4. That pair is then more available for sharing with a proton.
