Example: H3C - CH3 A molecule with a DOUBLE bond has 1 sigma bond a 1 pi bond (π). Example: H2C=CH2 A molecule with a TRIPLE bond has 1 sigma bond and 2 pi bonds.<br><b>References : </b><br> So very simple…look at the examples:

Single bond: 1 σ bond Double bond: 1 σ bond and 1 π bond Triple bond: 1 σ bond and 2 π bonds The information above is true for covalent bonds.<br><b>References : </b><br> Yes!

Single bond: 1 σ bond
Double bond: 1 σ bond and 1 π bond
Triple bond: 1 σ bond and 2 π bonds

The information above is true for covalent bonds.
