Descrizione generale

Bromomethane (methyl bromide) is the most effective soil fumigant for killing plant pests, its use is being phased out because its emissions from soil can lead to stratospheric ozone depletion. The bimolecular nucleophilic substitution (S(N)2) reaction of methyl bromide and OH- in aqueous solution has been investigated using a multilayered-representation quantum mechanical and molecular mechanics methodology.
