Chapter 12, Problem 36A

(a)

Interpretation Introduction

Interpretation:

The Lewis structure and resonating structures (if possible) of given molecule is to be drawn.

Concept introduction:

Lewis structure is a representation of a molecule which shows shared and unshared pair of electrons. It is helpful to determine the shape of a molecule.

Answer to Problem 36A

  

Explanation of Solution

Oxygen has six valence electrons. One electron is shared by each chlorine atom and two electron pairs are left unshared.

Its resonating structure is also possible as given.

(b)

Answer to Problem 36A

  

Explanation of Solution

Carbon has four valence electrons. Two electrons are shared by each oxygen atom and no electrons are left unshared.

(c)

Answer to Problem 36A

  

Resonating structures of $S{O}_3$are:

  

Explanation of Solution

Sulphur has six valence electrons. Each oxygen share two electrons with sulphur and no electrons are left unshared.

Seven resonating structures are possible for $S{O}_3$ . In main structure sulphur has more than eight electrons. So different resonating structures are drawn in which octet of sulphur is complete.
