SIR, con you please tell me why the both bonds are pi bonds in carbon .molecule

Dear student,

Pi bonds result from overlap of atomic orbitals that are in contact through two areas of overlap. Pi-bonds are more diffuse bonds than the sigma bonds. Electrons in pi bonds are sometimes referred to as pi electrons. Molecular fragments joined by a pi bond cannot rotate about that bond without breaking the pi bond, because rotation involves destroying the parallel orientation of the constituent p orbitals.

friend,

pi bonds will not exist without the presence of sigma bonds.

and hence, there is no carbon molecule with both pi bonds.
