Chapter 12, Problem 12.3TC

Interpretation Introduction

(a)

Interpretation:

Whether the statement, “atoms in molecular compounds are held together by covalent bonds” is true or false is to be identified. If false, the statement is to be re-written.

Concept introduction:

The covalent bond is formed by the sharing of the electrons between the atoms to achieve the stable electron configuration. The covalent bond is classified into three categories, single, double or triple bond.

Interpretation Introduction

(b)

Interpretation:

Whether the statement, “a lone pair of electrons is not shared between two atoms” is true or false is to be identified. If false, the statement is to be re-written.

Concept introduction:

The covalent bond is formed by the sharing of the electrons between the atoms to achieve the stable electron configuration. The covalent bond is classified into three categories, single, double or triple bond.

Interpretation Introduction

(c)

Interpretation:

Whether the statement, “an octet of valence electrons usually represents a low-energy state” is true or false is to be identified. If false, the statement is to be re-written.

Concept introduction:

The covalent bond is formed by the sharing of the electrons between the atoms to achieve the stable electron configuration. The covalent bond is classified into three categories, single, double or triple bond.
