sp/sp2 overlap
Answer
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.
1. Cross-overs from one end to the other give a strong \left( {\rm{\sigma }} \right)
2. Pi \left( {\rm{\pi }} \right) is formed when there are side-ways overlaps
Hybridization: This is a term that describes the merging of orbitals in order to create hybrid orbitals capable of bonding.
The number of sigma bonds that are attached to an atom can explain the hybridization.
Take a look at carbon atoms in their various hybridized states as shown below.
B
Below is the structure of cumulene.
The given structure clearly shows that there are two types of carbon atoms depending on the hybridization. {\rm{sp}} is used to identify inner carbons.
Below is the compound structure.
It is evident from the structure that there are four types orbital-overlaps.
1. {\rm{s}}{{\rm{p}}^{\rm{2}}}{\rm{ - s }}
2. {\rm{s}}{{\rm{p}}^{\rm{2}}}{\rm{ - sp}}
3. {\rm{sp - sp}}
4. {\rm{p - p}}Ans Part B
Below is an illustration of the Orbital-overlap that occurred in cumulene
