#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! 😀

lol i had just never heard of anthracene and was wondering if thats overkill

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.

It was in my textbook. We had to memorize that stuff when doing aromaticity.
