The number of electrons in the valence shell of the central atom of a molecule is 8. The molecule is

Options

A. `BCI_(3)`
B. `BeH_(2)`
C. `SCI_(2)`
D. `SF_(2)`

Answer

C

Explanation

`:underset(..)overset(..)(CI)-underset(..)overset(..)(S)-underset(..)overset(..)(CI):`
Number of lone pairs (Ip) on central atom i.e., S=2.
Number of bonding pairs (bp) on S=2 .
therefore Total number of electrons in valence shell,
= `2 xx ("No. of bp + no. of Ip")`
= `2 xx (2 + 2) = 8`
