scale of the actual molecule. In other words, two different bond lengths were
measured/observed for this compound (i.e. the C=C bond length is different than the C-C
length).
Expert Solution
Step 1
In cyclobutadiene two C=C bonds are present. But, due to ring strain the pi-orbital are orthogonal. That's why they don't undergo resonance heavily. That's why in cyclobutadiene two C-C bonds and two C=C bonds are present.
As we know single bond length is always greater than double bond length.
That's why in cyclobutadiene two C-C bond lengths are present.
