Question
Chapter 6, Problem 1CTQ
Interpretation Introduction
Interpretation:
The model of butane should be constructed.
Concept Introduction:
The spatial arrangement of atoms in a molecule obtained by rotation around carbon - carbon single bond is known as conformation.
Expert Solution & Answer
Explanation of Solution
In Newman conformation, the first carbon is represented by dot whereas the back carbon is represented by circle.
Staggered and eclipsed are the two type of conformation in Newman projection.
The molecule of butane can be represented by sawhorse, Newman projection, and wedge dash representation as follows:
The molecule of butane can be viewed from
represented as follows:
The representation of butane by wedge and dash representation is given as follows:

Draw a model of ethane. Imagine rotating the C-C single bond.
a.
Is there a change in the relative positions
of the different atoms as the C-C bond is
rotated? Yes or No?
b. Does the ethane molecule have more than
one conformation? Yes or No?
need help. Out of the four isomers shown above (menthol, isomenthol, neomenthol, and neoisomenthol), which isomer do you predict is the most stable? It may help to draw out each isomer in its most stable chair conformer to determine which has the most equatorial groups.
