Question

iv. Which of the following has the highest
basic strength
a. Trimethylamine b. Methylamine
c. Ammonia
d. Dimethylamine​

Answer 1

Answer:

c) Amonia has the highest basic strength in all of the bases

Answer 2

Answer:

The correct answer is Option D : Dimethylamine​

Explanation:

The tendency of a molecule to contribute electrons or hydroxide ions is known as basicity. The basicity of the molecule increases as the electrons become more readily available.

The following is the order of basicity that results from the combined action of +I and steric hindrance:

Dimethylamine > methylamine > trimethylamine

Therefore, dimethylamine has the highest basicity.

Basicity is inversely correlated with steric hindrance and the I, and directly proportional to the +I effect. Due to the ring's I, aniline has the least basicity of the four.
