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
