Name the cycloalkenes using systematic names. Consider alkene 1. A 5 carbon ring with a double bond between carbons 1 and 2. There is a methyl group on carbon 1 and 3.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
