Question

solve to find the number of Sigma and Pi Bonds in acetylene​

Answer 1

So basically, this the linear structure of Acetylene (which is a common name) for Ethyne has three sigma and two pi bonds.

Three sigma bond calculation:

C-H

C-H

C-C (nuclear overlapping)

Two pi bond calculation:

C-C

C-C

….both pi bond formed due to side-wise overlapping.
