Chapter 4, Problem 30P

Interpretation Introduction

Interpretation:

The number of rings in the cubane is to be determined using given formula.

Concept introduction:

Cubane is an artificial molecule in which there are 8 carbons at the corners of a cube, each carbon attached to one hydrogen atom.

The number of atoms in one ring will be 4 and the number of single bonds will be 8.

The number of rings can be calculated by:

$S-A+1=N$

Here, $S$ is number of single bonds, $A$ is number of atoms present in a ring, and $N$ is number of rings.
