#47 in destroyer... which compound below will absorb UV light at the longest wavelength? Anthracene?

Someone please tell me that's a little overkill

Longest wavelength=lowest frequency=most conjugated double bonds. Anthracene and Napthalene have a lot of conjugation..so which has more?

If they wanted shortest wavelength=highest frequency=triple bond without conjugation.

You can do it! :D

good explanation purplepanda. I'd just add that highest wavelength is most stable because its the one at the lowest energy level.

And i don't think its overkill to be familiar with anthracene and napthalene for instance.

Hmmm, I don't remember my teacher telling us anything about that kind of stuff.
