How many sigma and pi bond in Propyne
Accepted Answer
Propyne (CH3CCH) has 5 sigma bonds and 2 pi bonds.
Sigma bonds are formed by the direct overlap of atomic orbitals. There are 3 sigma bonds from each C-H bond, 1 sigma bond from the C-C bond, and 1 sigma bond from the C-C triple bond.
Pi bonds are formed by the sideways overlap of atomic orbitals. The triple bond in propyne contains two pi bonds.
