Which statement about bond rotations around C-C bonds in ethane and ethylene is correct?
  1.Rotation around  bond is easy because the orbital overlap does not change with rotation.
  2.Rotation around  bond is easy because there are p orbitals available in all directions of space.
  3.Rotation around  bond is very hard because the electron pairs from the adjacent bonds must pass by each other.
  4.Rotation around  bond is hard because the electrons are delocalized.
  5.Rotation around  bond is hindered because hydrogens on the adjacent carbons bump into each other.
