Assertion: Acetanilide is less basic than aniline.
Reason: Acetylation of aniline results in a decrease in electron density on nitrogen.
Explanation:
Assertion: Acetanilide is less basic than aniline.
The assertion states that acetanilide is less basic than aniline. Basicity refers to the ability of a molecule or ion to accept a proton (H+) or donate a pair of electrons. In this case, we are comparing the basicity of acetanilide and aniline.
Reason: Acetylation of aniline results in a decrease in electron density on nitrogen.
The reason provided is that the acetylation of aniline leads to a decrease in electron density on nitrogen. Acetylation refers to the process of introducing an acetyl group (CH3CO-) into a molecule. In this case, aniline (C6H5NH2) is acetylated to form acetanilide (C6H5NHCOCH3).
Explanation:
The reason provided is a correct explanation of the assertion. Let's break down the explanation into key points:
1. Aniline is a primary aromatic amine, consisting of a benzene ring attached to an amino group (-NH2). It can act as a weak base because the lone pair of electrons on the nitrogen atom can accept a proton.
2. Acetylation of aniline involves the substitution of the amino group with an acetyl group (-COCH3), resulting in the formation of acetanilide. This reaction is carried out using acetic anhydride (or acetyl chloride) as an acetylating agent.
3. The acetylation reaction leads to the formation of a new bond between the nitrogen atom of aniline and the carbon atom of the acetyl group. This bond formation causes a decrease in the electron density on the nitrogen atom.
4. The decrease in electron density on the nitrogen atom reduces its ability to accept a proton, thereby decreasing the basicity of the molecule. Acetanilide is therefore less basic than aniline.
In conclusion, the reason provided is a correct explanation of the assertion. Acetylation of aniline results in a decrease in electron density on nitrogen, which in turn reduces the basicity of the molecule, making acetanilide less basic than aniline. Hence, the correct answer is option 'b'.
