Chapter 9.8, Problem 9.13E

Interpretation Introduction

Interpretation:

The electron-dot formula of given molecule has to be explained.

Concept introduction:

Sulfur tetrafluoride, ${\text{SF}}_{\text{4}}$, is a colorless gas.

All stable molecules attain the noble gas and octet arrangement.  So that molecule is more stable and less reactive nature.

According to Octet rule eight electrons in the outer most shell that atoms is most stable arrangement in other atoms have less than eight electrons.

Rules and steps given in text; valence electrons = group number (from periodic table); central atom is S (least electronegative).  Central atom is S, from number considerations only.
