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 contain one σ bond and one π bond.[Step 4]:Therefore number of C-H  σ bonds = 10number of  C-C  σ bonds = 7number of  C=C  σ bonds = 6number of  C=C  π bonds = 6
