Question

The basic character of etyl amine diethyl amine and triethylamine is in increasing order is

Answer 1

Answer:

diethylamine > triethylamine > ethyl amine ..

Explanation:

1. In aliphatic amines, the −NH group is attached to an alkyl group which is an electron donating group i.e, they have +I effect. So, the lone pair of electrons on nitrogen are readily available. Therefore aliphatic amines are more basic than aromatic amines.

2. The presence of alkyl groups undoubtedly increases the basicity of 2

• amine in comparison to 1
• amine due to increased +I effect.

3. However, the presence of 3 alkyl groups in case of 3

• amine , leads to steric hindrance and thus the lone pair on −N atom is less available for donation.

Hence the order is :

diethylamine > triethylamine > ethyl amine ..
