Question

Which is a strong base?(please explain)

CH3CH2NH2 or CH3CH2NHCH3

Answer 1

Answer #1

CH3CH2NH2, there is one alkyl group (CH3-CH2-) that is attached to N.

This increases electron density on N by Inductive effect.

CH3CH2NHCH3, there are 2 alkyl group (CH3CH2- and CH3-) that is attached to N.

This increases electron density on N by Inductive effect more than CH3CH2NH2.

So, electron density is more on CH3CH2NHCH3 and hence this is stronger base

Answer: CH3CH2NHCH3
