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

Question

Cl
|
C'triple bond'C
|
Cl

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

Answer 1

Answered below. What does QMM stand for?

Answer 2

i believe it stands for quantum mechanical model. i guess my teacher shortened it but she just describes it as the flower model.
