Hint: The single bonds in a compound are known as the bonds. If there are double bonds in a compound then one bond is bond and one is the bond. If there are triple bonds in a compound then one bond is the bond and two are the bonds.
Complete step by step solution:
We know that the molecule has covalent bonds there are sigma bonds and pi bonds. The sigma bonds are represented by and the pi bonds are represented by .
The bond formed between two atoms by the axial overlap of the atomic orbitals along the intermolecular axis is known as the sigma bond.
The bond formed by the lateral overlap of the atomic orbitals at right angles to the intermolecular axis is known as the pi bond.
1. Consider the compound :
The structure of is as follows:
- The structure of contains three single bonds and three double bonds.
- Three single bonds indicate that there are three bonds. And three double bonds indicate that there are three bonds and three bonds. Thus, there are six bonds and three bonds.
- Thus, has six bonds and three bonds.
2. Consider the compound :
The structure of is as follows:
- The structure of contains eighteen single bonds.
- Eighteen single bonds indicate that there are eighteen bonds. Thus, there are eighteen bonds and zero bonds.
- Thus, has eighteen bonds and zero bonds.
3. Consider the compound :
The structure of is as follows:
- The structure of contains four single bonds.
- Four single bonds indicate that there are four bonds. Thus, there are four bonds and zero bonds.
- Thus, has four bonds and zero bonds.
4. Consider the compound :
The structure of is as follows:
- The structure of contains four single bonds and two double bonds.
- Four single bonds indicate that there are four bonds. And two double bonds indicate that there are two bonds and two bonds. Thus, there are six bonds and two bonds.
- Thus, has six bonds and two bonds.
5. Consider the compound :
The structure of is as follows:
- The structure of contains five single bonds and one double bond.
- Five single bonds indicate that there are five bonds. And one double bond indicates that there is one bond and one bond. Thus, there are six bonds and one bond.
- Thus, has six bonds and one bonds.
6. Consider the compound :
The structure of is as follows:
- The structure of contains seven single bonds and one double bond.
- Seven single bonds indicate that there are seven bonds. And one double bond indicates that there is one bond and one bond. Thus, there are six bonds and one bond.
- Thus, has eight bonds and one bonds.
Note:
The sigma bond overlapping is very large and thus, the sigma bond is stronger. The overlapping of pi bonds is weak and thus, pi bond is weaker. The sigma bond has one-electron cloud and the pi bond has a two-electron cloud.
