Question

Deference between axial and sideways overlapping

Answer 1

Answer:

When a bond is formed between two atoms by the overlap of their atomic orbitals along the internuclear axis (end to end or head on overlap), then it is called axial overlapping.

Explanation:

The p orbitals on each carbon aren't pointing towards each other, are overlapping sideways. This sideways overlap also creates a molecular orbital, but of a different kind. In this one the electrons aren't held on the line between the two nuclei, but above and below the plane of the molecule.
