Identify the correct count of -bonds, -bonds, and lone pairs of electrons present in a molecule of aniline.
Options
- A
- B
- C
- D
Correct answer
C.
Step-by-step solution
The chemical formula of aniline is .
The structure consists of a benzene ring attached to an amino group ().
Number of -bonds:
C-C bonds in the benzene ring =
C-H bonds in the benzene ring =
C-N bond =
N-H bonds =
Total -bonds =
Number of -bonds:
C=C double bonds in the benzene ring =
Total -bonds =
Number of lone pairs:
Nitrogen has valence electrons. It shares electrons in bonding ( with carbon, with hydrogen), leaving non-bonding electrons.
Total lone pairs =
Thus, the count of -bonds, -bonds, and lone pairs is , , and respectively.
