energy.​

Answer 1

Answer:

change the number of life

Answer 2

The energy required to rotate ethane molecule  about the carbon-carbon bond is called torsional energy.​

• There are different conformations (i.e. geometric arrangements) of carbon-containing species namely staggered, eclipsed, and gauche conformations.
• In eclipsed conformation, the dihedral angle is 0° while in staggered conformation, the dihedral angle is 180°. There exists a torsional strain which is a barrier to the rotation between the two forms.  
• The energy required to overcome this barrier is called torsional energy.
