Chapter 7, Problem 16P

(a)

Interpretation Introduction

Interpretation:

The logic should be explained for the suggestion of similar structure of ${\text{C}}_{60}$ and ${\text{C}}_{\text{12}}{\text{B}}_{\text{24}}{\text{N}}_{\text{24}}$ by comparing their number of valence electrons.

Concept Introduction:

The electrons present in the outermost energy level or shell is known as valence electrons. These electrons are available for bonding and outermost shell is known as valence shell.

(b)

Interpretation Introduction

Interpretation:

The most symmetric pattern of carbon, boron and nitrogen atoms in ${\text{C}}_{\text{12}}{\text{B}}_{\text{24}}{\text{N}}_{\text{24}}$ should be determined to occupy the 60 atom sites in fullerenes structure along with the location where double bond could be present in the structure.

Concept Introduction:

Fullerene molecular formula: ${\text{C}}_{60}$

Fullerene has 60 carbon atoms and its structure is arranged in a closed net having 12 pentagonal and 12 hexagonal faces to form cage like structure.
