Chapter 4, Problem 1IA.5Q

Summary Introduction

To determine:

The atom that is always at the intersection of two line segments in the skeletal structure is to be identified.

Introduction:

The skeletal structure shows the bonds between the carbon atoms in the form of lines in two dimensions. The connection between the two carbons is indicated by a line.

The number of $\text{C-H}$ bonds to any carbon atoms is equal to four minus the bonds formed by the carbon as carbon always involved four bonds.
