Question

No. of Signa Bonds present in CH3-CH2-CH2-OH​

Answer 1

Answer:

No. of Signa Bonds present in CH₃-CH₂-CH₂-OH is 11.

Explanation:

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

Generally, the single bonds are sigma bonds.

Here,

sigma C−C bonds =2, sigma C−H bonds =7, O-H sigma bond =1, C-H sigma bond=1

Total sigma bond=11

SHORTCUT METHOD

Total no of sigma bond =total no of atom -1 + no of rings =12-1+0=11

Answer 2

11 sigma bonds present
