How the UV spectrum of the conjugated product, cholest- 4 -ene- 3 -one is different from that of cholesterol is to be described. Concept introduction: In ultraviolet (UV) spectra of aldehydes and ketones , the strongest absorptions are the ones that results from π to π * electronic transition. In alkenes , these observations are seen at λ max > 200 nm only if the carbonyl double bond is in conjugation with another double bond in the molecule.
