How can an eclipsed conformation of ethane be converted into a staggered conformation ?

The correct statement regarding the comparison of staggered and eclipsed conformations of ethane is -

Draw the eclipsed and staggered conformations of ethane and comment on the relative stabilities of the two conformations.

The correct statement regarding the comparison of staggered and eclipsed conformation of ethane , is -

Conformations are different arrangements of atoms that are interconverted by rotation about single bond. In eclipsed conformation the C-H bond on one carbon is directly aligned with C-H bond on the adjacent carbon. The angle that separates a bond on one atom from a bond on a adjacent atom is called a dihedral angle. A staggered conformation with two larger groups 180^@ from each other is called anti. A stagged conformation with two larger group 60^@ from each other is called gauche. Identify the most stable conformer of 2-fluoro ethanol among the following :

Draw the eclipsed and staggered conformations of ethane using Newman projection formula.

Arrange the following conformations of n-butane according to their increasing stability : gauche-staggered (I), fully eclipsed (II),eclipsed (III) and -staggered (IV).
