Chapter 11, Problem 11A.16E

(a)

Interpretation Introduction

Interpretation:

The line structure of 2,2,3,3-tetramethylhexane has to be drawn.

Concept Introduction:

Line structure:  Line structure is a simplest representation of a hydrocarbon.  In line structure, the chain of carbon atoms is shown as a zigzag line.  The end of each short line in the zigzag represents a carbon atom.  Since the carbon nearly always has a valence of four in organic compounds, it is not necessary to show the hydrogen atoms.

(b)

Interpretation Introduction

Interpretation:

The line structure of the trityl cation has to be given.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The line structure of butadiene has to be given.

Concept Introduction:

Refer to part (a).
