Elimination,When haloalkanes (other than halomethanes) undergo nucleophilic substitution, there is invariably a side reaction involving the formation of an alkene (or alkenes). For example, alkaline hydrolysis of 2-iodopropane is accompanied by formation of some propene

主講人

Nucleophilic Reactions of Carbonyl Compounds,Aldehydes and ketones have a polar structure (chapter 1) and as a result the electron-deficient carbonyl carbon atom is susceptible to nucleophilic attack

Itinerant

Electrophilic Addition Reactions of Alkenes and Alkynes,Alkenes have a planar structure and, as you will remember, the so called ‘double bond’ in fact consists of a . (end-on overlap of s. hybrid atomic orbitals) and a . (sideways overlap of 2. atomic orbitals).

Aromatic Electrophilic Substitution, electrophilic substitution. With six pi electrons in a circular molecular orbital above and below the plane of the nucleus, benzene is a molecule with a high pi electron density and is therefore nucleophilic.
