Can you start by telling us the definition of cyclo from your textbook? If you think the definition applies, can you tell us how? If you think it doesn't apply, can you tell us what term does? You be better off, come exam time, if you try to understand some underlying concepts. You probably will see a different, but similar, molecule come exam time.
