Identify the correct count of σ\sigma-bonds, π\pi-bonds, and lone pairs of electrons present in a molecule of aniline.

Options

  1. A13, 3, 113,\ 3,\ 1
  2. B14, 3, 014,\ 3,\ 0
  3. C14, 3, 114,\ 3,\ 1
  4. D12, 3, 112,\ 3,\ 1

Correct answer

C. 14, 3, 114,\ 3,\ 1

Step-by-step solution

The chemical formula of aniline is C6H5NH2C_6H_5NH_2.

The structure consists of a benzene ring attached to an amino group (−NH2-NH_2).

Number of σ\sigma-bonds:
C-C bonds in the benzene ring = 66
C-H bonds in the benzene ring = 55
C-N bond = 11
N-H bonds = 22
Total σ\sigma-bonds = 6+5+1+2=146 + 5 + 1 + 2 = 14

Number of π\pi-bonds:
C=C double bonds in the benzene ring = 33
Total π\pi-bonds = 33

Number of lone pairs:
Nitrogen has 55 valence electrons. It shares 33 electrons in bonding (11 with carbon, 22 with hydrogen), leaving 22 non-bonding electrons.
Total lone pairs = 11

Thus, the count of σ\sigma-bonds, π\pi-bonds, and lone pairs is 1414, 33, and 11 respectively.

Answer: 14, 3, 114,\ 3,\ 1
