How do I find out if a compound expected to have pi to pi antibonding absorptions in the 200-400 nm range, just by looking at the formula of the compound?

Does it have pi-bonds?

Is having a pi bond make a compound has a pi to pi antibonding uv absorption?

I may be going on a tangent, but do you know what conjugated pi bonds are? There is a relationship between the number of conjugated pi bonds and the wavelength.

yea i know about conjugated pi bonds! What is that relationship?

The difference in energy falls as the number of conjugated bonds increases.
