(a)
Interpretation:
The Lewis structure of
Concept introduction:
The strategy for drawing Lewis structure is mention below.
- Calculate the number of valence electrons present in the molecule.
- Calculate the electron pairs by dividing number of valence electrons by 2.
- Determine the bond pairs.
- Determine the lone pairs.
- Check whether the central atom satisfies octet rule.
