Question

Describe the conformation of n butane and cyclo bexane​

Answer 1

Answer:

However, because there is no methyl-to-methyl eclipsing, it is lower in energy than eclipsed conformation A. One more 60 rotation produces the 'anti' conformation, where the two methyl groups are positioned opposite each other and steric repulsion is minimized. This is the lowest energy conformation for butane.......

Answer 2

Answer:

When the dihedral angle = 0° or 360°, (syn conformation) in butane, the two methyl groups are in close proximity with the molecule, therefore the potential energy is at its highest. ... In the anti conformation (when the dihedral angle = 180°) the potential energy is at its lowest, therefore the most stable.
