Question

how to find sigma and pi bonds?​

Answer 1

Answer:

Always the first bond formed is sigma bond and rest of all is pi bond.

If we look at the above example of , bond between C and H is sigma bond , and first bond between C and N is single bond and rest two bonds are pi bond.

So total of 2 sigma and 2 pi bonds are present.

Answer 2

Answer:

The sigma bond is formed by the head-on overlap of two sp2 orbitals. The pi bond is formed by the side-on overlap of two 2p orbitals. A triple bond contains one sigma bond and 2 pi bonds. In acetylene, the C≡C triple bond consists of a sigma bond and two pi bonds.
