Answer “What types of orbital overlap occur in cumulene?”
Concepts
The orbital overlapping concept can be used to explain the concept of bonding between atoms within molecules. These overlaps can be divided into two types according to the orientation of orbitals within the atoms.
- End-on-end overlaps, gives a strong sigma (σ) bond
- Side-ways overlaps results in the formation of (π) bond; these overlaps are named after their orbitals.
Fundamentals
Hybridization: Hybridization refers to the process of combining individual orbitals in order to create hybrid orbitals capable of bonding.
Hybridization of an atom can be explained by the number of sigma bonds attached to that atom.
Consider carbon atoms in its various hybridized state as shown below:

The number of sigma bonds attached to the atom | Hybridization | The remaining unhybridized p-orbital in the atom |
2 | sp | 2 |
3 | sp2 | 1 |
4 | sp3 | 0 |
