Draw the Newman's projections of the eclipsed and staggered conformations of n-butane.

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

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

Draw the sawhorse projections for eclipsed and staggered forms of a ethane molecule.

The most stable conformation of n- butane is

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.

Draw Sawhorse and Newman's projections of the different conformers 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. i) Represent Sawhorse and Newman projection formulae of staggered and eclipsed conformation of ethane.

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.

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