.Identify the most basic compound from the following.a)C6H5NH2b)(C6H5)2NHc)CH3NH2d)(CH3)2NHCorrect answer is option 'D'. Can you explain this answer?

Question

Answer

In a and b lone pair are in resonance
+I group of d is more than c which increase electron density on nitrogen

Answer

CH3 is a electron donating group and benzene is a electron withdrawing group so option A and B are easily eliminated. Among C and D the +I effect of CH3 dominates over the stearic hindrance factor so D is most basic.

Answer

2 cH3 Group.Which are electron donating group

Answer

The most basic compound from the given options is (CH3)2NH, or dimethylamine.

Explanation:

Basicity refers to the ability of a compound to donate an electron pair. Compounds with lone pairs of electrons on the central atom or atoms tend to be basic. The presence of a lone pair of electrons allows the compound to accept a proton and form a coordinate covalent bond.

To determine the most basic compound from the options provided, we need to look at the structures and identify the compounds with lone pairs of electrons on the central atom.

a) C6H5NH2 (aniline):
Aniline has a lone pair of electrons on the nitrogen atom, making it a base. However, it is not the most basic compound among the given options.

b) (C6H5)2NH (diphenylamine):
Diphenylamine also has a lone pair of electrons on the central nitrogen atom, making it a base. However, it is not the most basic compound among the given options.

c) CH3NH2 (methylamine):
Methylamine has a lone pair of electrons on the nitrogen atom, making it a base. It is more basic than aniline and diphenylamine.

d) (CH3)2NH (dimethylamine):
Dimethylamine has two lone pairs of electrons on the central nitrogen atom, making it more basic than methylamine and the other options. The presence of two lone pairs of electrons increases the electron density on the nitrogen atom, enhancing its basicity.

Therefore, the most basic compound among the given options is (CH3)2NH (dimethylamine).
