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. Which of the following is gauche conformer ?
