WebIn single-bonded carbon, this is easy: overlap some pair of the 2p orbitals on the same axis. For double-bonded carbon, you overlap two on the same axis (imagine this as the x-axis) between the atoms (a sigma bond) and two of the orbitals at a 90 degree angle to that (a sigma bond). Triple bond, same deal. WebAnswer (1 of 4): Formation of a sigma bond involves head on overlapping i.e. overlapping of orbitals along their internuclear axis, giving rise to maximum electron density on the axis. Thus free rotation around sigma bond is possible. Formation of a pi bond involves lateral or sideways overlappi...
