(a) Interpretation: The number of electron groups that surround the triple bonded C in Figure 2-1a is to be determined. Concept introduction: A group of electrons around an atom is a lone pair or a bond with another atom. The bond, whether a C-C bond, a C=C bond, or a C ≡ C bond, counts as just one electron group. So electron groups around an atom can also be counted as the number of atoms bonded to it plus any lone pairs on it.

Interpretation Introduction

(a)

Interpretation:

The number of electron groups that surround the triple bonded C in Figure 2-1a is to be determined.

Concept introduction:

A group of electrons around an atom is a lone pair or a bond with another atom. The bond, whether a C-C bond, a C=C bond, or a C≡C bond, counts as just one electron group. So electron groups around an atom can also be counted as the number of atoms bonded to it plus any lone pairs on it.

Interpretation Introduction

(b)

Interpretation:

The number of electron groups that surround the central C in Figure 2-1b is to be determined.

Concept introduction:

A group of electrons around an atom is a lone pair or a bond with another atom. The bond, whether a C-C bond, a C=C bond, or a C≡C bond, counts as just one electron group. So electron groups around an atom can also be counted as the number of atoms bonded to it plus any lone pairs on it.

Interpretation Introduction

(c)

Interpretation:

The number of electron groups that surround each C in Figure 2-1c is to be determined.

Concept introduction:

A group of electrons around an atom is a lone pair or a bond with another atom. The bond, whether a C-C bond, a C=C bond, or a C≡C bond, counts as just one electron group. So electron groups around an atom can also be counted as the number of atoms bonded to it plus any lone pairs on it.
