On change from the staggered form to the eclipsed form in the ethane molecule conformation, what happens to the electron cloud of carbon-hydrogen bonds?

Text Solution

Verified by Experts

The carbon -hydrogen bonded electron cloud comes closer to each other resulting in increase in electron cloud repulsions consequently increasing the torsional strain.
