The staggered structure is the structure of lower energy than-xA0-eclipsed structure- The relative energy required for-xA0-complete a rotation in ethane is called the energy barrier to rotation- and it is about 3 kcal-mol- That is- the eclipsed structure is 3 kcal higher in energy than the staggered structure-

The energy barrier to free rotation about carbon carbon bond of ethane is about:40 kJ mol−130 kJ mol−13 kcal mol−13 kJ mol−1

The energy barrier to free rotation about carbon carbon bond of ethane is about:
${40 k J m o l}^{- 1}$
${30 k J m o l}^{- 1}$
${3 k c a l m o l}^{- 1}$
${3 k J m o l}^{- 1}$
