Number of π bonds and σ bonds in the following structure is
[Step 1]:
All C-H bonds are single covalent bonds are σ bonds.
[Step 2]:
All C-C single covalent bonds are σ bonds.
[Step 3]:
C=C double covalent bond contains one σ bond and one π bond.
[Step 4]:
Therefore, number of C-H σ bonds = 10
number of C-C σ bonds = 7
number of C=C σ bonds = 6
number of C=C π bonds = 6
