Concept explainers
(a)
Interpretation:
The conformation of ethane which is downhill in terms of potential energy from the eclipsed confirmation should be determined.
Concept Introduction:
A diagram which is used to denote the specific conformation of a molecule is known as Newman projection. It is classified as: Staggered conformation and Eclipsed conformation.
(b)
Interpretation:
The repulsive forces which will cause ethane in the eclipsed conformation to quickly adopt the staggered conformation should be determined.
Concept Introduction:
A diagram which is used to denote the specific conformation of a molecule is known as Newman projection. It is classified as: Staggered conformation and Eclipsed conformation.
The forces which hold the two molecules with together are known as intermolecular forces.

- Consider the molecule 1-bromo-2-methylbutane. C3 and C4 should be drawn as Et as in theexample. This group is called an ethyl group and can be considered a sphere about twice the sizeof a methyl group. Draw the following Newman projections sighting down the C1C2 bond... a. The lowest potential energy conformation. b. The highest potential energy staggered conformation.arrow_forwarda model of cyclohexane in a chair conformation, and explain why the names “axial” and“equatorial’ are appropriate.arrow_forwarda. b. For the following two pairs of molecules, (1) Draw out the chair conformation for each molecule, flip the ring if it is possible. (2) Compare both molecules to circle out which one is more stable. (3) Identify their relationship as: constitutional isomer, conformational isomer, stereoisomer or identical. (4) Find all the chiral center on each molecule and label them. Br.. Ax < and and H.
