Question

calculate the sigma and pi bond in 2-methylpropene​

Answer 1

Answer:

Structure of 2-methyl propene is shown in attachment.

Af,ter expanding it in long form in which all bonds are shown we can easily calculate the Sigma and Pi bonds in the required structure very easily as shown in the attachment.

Remember that pi bond is only found in multiple Bonds.

After expand the structure we observed that number of sigma bond is 11 and number of Pi bond is only one [as only one multiple bond is present]
