WebbThe C=C π bond of an alkene is higher in energy than the C—H or C—C σ bond. As a result it can act as a nucleophile towards various electrophilic species. When a C=C π bond acts … WebbAnswer: Amazingly, nucleophilicity or electrophilicity is not as simple as being a pi bond or not. The reactivity around a chemical bond, being it either a sigma, pi or even delta bond, …

The particle in a box (PiB) model can be applied to electrons which move freely in a molecule such as π electrons. 1,3-butadiene CH2=CH-CH=CH2 has an absorption peak in the UV-Vis spectrum at 290 nm. This peaks is assigned to the π → π* transition of the lowest energy. This transition is also called the HOMO → LUMO transition.
