Determining the pi to pi antibonding UV absorptions?

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?

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3.

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.

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