Question

How do you identify sigma and pi bonds?

Answer 1

Usually, all bonds between atoms in most organic compounds contain one sigma bond each. If it is a single bond, it contains only sigma bond. Double and Triple bonds, however, contains sigma and pi bonds. Double bonds have one each, and triple bonds have one sigma bond and two pi bonds.

1 single bond = 1 sigma bond

1 double bond = 1 sigma bond + 1 pi bond

1 triple bond = 1 sigma bond + 2 pi bonds
