Alkyl Halides Reactions MDCAT Quiz: Alkyl Halides Reactions are important to MDCAT students as the building blocks for quite a number of reactions in organic chemistry. Among the important types of reactions that take place in alkyl halides are nucleophilic substitution and elimination. In nucleophilic substitution, the halogen atom is replaced by the nucleophile, a reaction that could take place in either SN1 (unimolecular nucleophilic substitution) or SN2 (bimolecular nucleophilic substitution) mechanism, depending on the nature of the alkyl halide that may be primary, secondary, or tertiary. In the case of elimination reactions, the alkyl halide may lose a halogen atom and a hydrogen atom, thus forming alkenes. In fact, their nature is controlled by such variables as the structure of the alkyl halide, the nature of the nucleophile or base, and reaction conditions. The set of reactions referred to here synthesizes most of the organic compounds very well and are normally tested in MDCAT subjects.
