Question

Number of o and it bonds present in following molecule
respectively are

a 9 sigma and 6π bonds
b. 9 sigma and 12πbonds
c. 15 sigma and 6π bond
d. 15 sigma and 9π bonds​

Answer 1

Answer:

Sigma bonds (σ) are formed by the coaxial overlapping of the two orbitals of equal energies. Generally, the single bonds are sigma bonds. 

Pi bonds (π) are formed by the lateral overlapping of two orbitals with equal energies.

Double bond contains one sigma bond and one pi bond whereas triple bond contains one sigma bond and two pi bond. 

Here,

sigma C−C bonds =3, sigma C−H bonds =2+1+3=6 , pi C−C bonds =1+1=2 

Hence, option B is correct.
