A spacial arrangements of atoms which can be converted into one another by rotation arround a C-C single bond are called conformations.
i) Represent Sawhorse and Newman projection formulae of staggered and eclipsed conformation of ethane.

Draw the Newman projections for staggered and eclipsed conformations of ethane.

A spacial arrangements of atoms which can be converted into one another by rotation arround a C-C single bond are called conformations. ii) Comapare the stabilities of staggered and eclipsed conformations.

Draw the Newman projections of the eclipsed and staggered conformations of ethane molecule.

Conformations are those special arrangements which are obtained by rotation around sigma bonds. Draw the staggered and eclipsed conformation of ethane.

Isomers which can be interconverted by rotation of the moleucle around single bond are (1) Geometrical isomers (2) Enantiomers (3) Conformers (4) Diastereomers

Controlled oxidation of alkanes in the presence of suitable catalysts give a variety of products. Free rotation about a carbon - carbon single bond is permitted in an alkane molecule. What are conformers? Draw the structure of the eclipsed and staggered conformers of ethane in Sawhorse and Newman projection and explain their relative stability.

Free rotation is possible with respect to a C-C bond in the case of alkanes. b) Draw Newman's projections of the two conformers of ethane. Which among these is more stable? Justify.

Free rotation is possible with respect to a C-C bond in the case of alkanes. a) The repulsive interaction between the adjacent bonds in a conformation is called…...
