Question
Chapter 6, Problem 6.19P
Interpretation Introduction
Interpretation:
The anti-conformation of butane as an isolated structure has any stereocenters or not is to be determined. The stereo-centers in the anti-conformation of butane are to be identified if present.
Concept introduction:
A carbon atom that has four nonequivalent atoms or groups attached to it is known as the chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers. A carbon atom that does not have four nonequivalent atoms or groups attached to it is known as an achiral carbon atom.

The following are representations of two forms of glucose. The six-membered ring is known to exist in a chair conformation in each form. Draw clear representations of the most stable conformation of each. Are they two different conformations of the same molecule, or are they stereoisomers that cannot be interconverted by rotation about single bonds? Which substituents (if any) occupy axial sites?
Describe the conformations of the following:
E) Gauche conformation of ethane,
(ü) felipsed conformation of ethene,
(iii) Staggered conformation of propane,
(iv) Syn- and anti-conformation of butane.
Determine whether the structures in each set represent the same molecule, cis-trans isomers, or constitutional isomers. If they are the same molecule, determine whether they are in
the same or different conformations as a result from rotation about a carbon-carbon single bond.
