The number of electrons is the valence shell of the central atom of a molecules is 8 . The molecule is
- A \(\mathrm{BCl}_3\)
- B \(\mathrm{BeH}_2\)
- C \(\mathrm{SCl}_2\)
- D \(\mathrm{SF}_6\)
Answer & Solution
Correct Answer
(C) \(\mathrm{SCl}_2\)
Step-by-step Solution
Detailed explanation
In \(\mathrm{SCl}_2\), number of lone pairs on \(\mathrm{S}=\frac{6-2(1)}{2}=2\) \(\therefore\) Total number of pairs of electrons \(=2\) bonding +2 lone pairs \(=4\) pairs \(\therefore\) Total number of electrons in valency shell \(=4 \times 2=8\)
