Chapter 2, Problem 2.46AP

Interpretation Introduction

(a)

Interpretation:

The number of different compounds with the formula ${\text{C}}_{\text{5}}{\text{H}}_{\text{11}}\text{Cl}$ is to be stated. The Lewis structures and the line-and-wedge formulas of the compounds are to be drawn. Whether the result is altered or not is to be stated.

Concept introduction:

Newman projection is a way of representing the groups attached to carbon atoms in the $\text{C-C}$ bonds. This is used to determine the interaction between the groups attached to carbon atoms and the dihedral angle. The front carbon atom in the Newman projection is represented by the dot and the end on carbon atom is represented by the circle. The groups attached to the carbon atoms are then drawn by the line.

The line-and-wedge representation is used to show the molecule in three dimensions.

The sawhorse representation is used to show the above carbon atom on right side in a molecule.

Interpretation Introduction

(b)

Interpretation:

The number of different compounds obtained by replacing one hydrogen with chlorine in $\text{2, 2dimethylbutane}$ is to be stated. The Lewis structures and the line-and-wedge formulas of the compounds are to be drawn. Whether the result is altered or not is to be stated.
