MCQ
Basic strength of different alkyl amines depends upon:
- A$+I$ effect
- BSteric effect
- CSolvation effect
- ✓All of these
✓
Answer
Correct option: D.
All of these
The basic strength of different alkyl amines depends on many factors like:
- $+I$ effect is the polarization of a sigma bond due to electron donating effect of adjacent groups or atoms.
- In water, the ammonium salts of primary and secondary amines undergo solvation effects due to hydrogen bonding to a much greater degree than ammonium salts of tertiary amines.
- Steric effect is the effect faced by incoming group or hydrogen by the already present bulky $−R$ groups on the Nitrogen atom.
