Which from following molecules has two lone pair of electrons in valence shell of its central atom?
- A \(\mathrm{SO}_2\)
- B \(\mathrm{NH}_3\)
- C \(\mathrm{H}_2 \mathrm{O}\)
- D \(\mathrm{SF}_4\)
Answer & Solution
Correct Answer
(C) \(\mathrm{H}_2 \mathrm{O}\)
Step-by-step Solution
Detailed explanation
In \(\mathrm{H}_2 \mathrm{O}\), central atom oxygen ( 6 valence electrons), attains a stable octet by bonding with 2 hydrogen atoms, resulting in 2 bond pairs and 2 lone pairs (four non-bonding electrons).
