Chapter 9.6, Problem 9.11E

(a)

Interpretation Introduction

Interpretation:

The Lewis electron-dot formula given compounds has to be drawn.

Concept introduction:

Lewis electron-dot symbols.

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

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