    In chemistry pi bonds are the covalent chemical bonds formed between the two neighboring atoms unbounded P orbitals.
    An unbounded P orbitals electron in one atom forms an electron pair with the neighboring atoms unbound parallel P orbital electron. This electron pairs forms the pi bond. Double bond and triple bonds are usually made up of  single sigma bond and one or two Pi bonds. Pi bonds are generally denoted by the Greek letter ( ) . Pi bonds are usually weaker than the sigma bonds.
