Which of the following is gauche conformer?

In which of the following molecules gauche form is more stable than their anti form?

Which of the following is most stable conformer?

Which of the following is most stable conformation?

Which of the following is correct regarding stability of conformations of n-butane about C_(2)-C bond Anti (I) gauche (II) partially eclipsed (III) fülly eclipsed (IV)

Which of the following is true regarding the following conformations of butane.

Conformations are different arragements of atoms htat 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. In staggered conformation, the C-H bond on one carbon bisect the H-C-H bond angle on adjacent carbon. The angle that seperates a bond on one atom form 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 staggered conformation with two larger group 60^(@) from each other is called gauche Which of the following conformer of butane has minimum energy?

Which of the following can show conformational isomerism:
