Question

C-N bond length in aromatic amines are shorter than that in aliphatic amines. reason.

Answer 1

An aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines, but also many more complex aromatic rings and many amine substituents beyond NH₂. Such compounds occur widely. 

Answer 2

Answer:

Aromatic amines' C-N bonds are shorter than those of aliphatic amines. Reason.

An electron withdrawing group is the phenyl group. As the electron density at the carbon atom diminishes, the C-N bond becomes more polar.

Explanation:

• The carbon-nitrogen bond in aromatic amines has a double bond character due to the electron-donating effect (+R-effect) of the 'NH (2)' group.
• In aliphatic amines, on the other hand, the carbon-nitrogen connection is merely a single bond.

• The carbon-nitrogen bond in aromatic amines (refer to resonating structures of aniline on page 15/43) acquires some partial double bond character due to the +R effect of the '-NH 2' group.
• In aliphatic amines, on the other hand, the carbon nitrogen bond is merely a single bond.
