True a pi bond consist of two pairs of electrons and a sigma bond consists of one pair of electrons.
Pi bonds can form in double and triple bonds but do not form in single bonds in most cases.
They are stronger than sigma bonds. They are formed from side to side overlap of p orbitals They are the only bonds found in a multiple bond.
In general, single bonds between atoms are always sigma bonds. Double bonds are comprised of one sigma and one pi bond. Triple bonds are comprised of one sigma bond and two pi bonds.
