Acetone shows maximum absorption at 279 NM in hexane where's its lambda λmax in water is 265 nm. Explain

The electronic transitions in organic compounds and some other compounds can be determined by ultraviolet–visible spectroscopy, provided that transitions in the ultraviolet (UV) or visible range of the electromagnetic spectrum...

The carbonyl groups, in this case keto groups are considered as functional groups and should be denoted by secondary suffix, one, whenever there are no other functional groups with higher...

An electron in a bonding σ orbital is excited to the corresponding antibonding orbital. The energy required is large. For example, methane (which has only C-H bonds, and can only...
