I have to draw the QMM of CL2C2. For the Lewis structure i think that the two C ayoms form a triple bond and the Cl atoms form single bonds.

Therefore i think that the central C atom hybridizes into sp.

if this is correct, my question is how do i know which p orbital on C to form my sigma bonds for the Cl atoms. Does it matter?

thanks

One electron from one of the Cl atoms bonds with one of the free p orbitals of the C atom (either one), and the other Cl p electron bonds with the other free p orbital of the C atom.
