Mar 26, 2014  · Nucleophilic substitution is a process in which a leaving group on a compound is replaced by a nucleophile. There are two different types of substitution reactions. They are known as SN1 and SN2 reactions. There are many differences between these two reactions. For example, SN1 are two step reactions, involving the formation of a carbocation intermediate, followed by a nucleophilic attack.

Alkyl halides can undergo two major types of reactions – substitution and/or elimination. The substitution reaction is called a Nucleophilic Substitution reaction because the electrophilic alkyl halide forms a new bond with the nucleophile which substitutes for (replaces) the halogen at the alpha-carbon.

Organic Chemistry Ch. 7: Alkyl Halides and Nucleophilic Substitution. • It is generally true that the stronger base is the stronger nucleophile. • In polar protic solvents, however, nucleophilicity increases with increasing size of an anion (opposite to basicity). • Steric hindrance decreases nucleophilicity without decreasing basicity, making (CH3)3CO- a stronger base but a weaker nucleophile than.

Methyl and primary alcohols are converted to alkyl halides via SN2 reaction according to the general mechanism shown below. The I– and Br– are strong enough nucleophiles to attack the primary carbon and the +OH2, in turn, is an excellent leaving group in form of neutral water molecule.

The terminology S N 1 stands for “substitution nucleophilic unimolecular.” S N 2 mechanism. The alkyl halide substrate contains a polarized carbon halogen bond. The S N 2 mechanism begins when an electron pair of the nucleophile attacks the back lobe of the leaving group. Carbon in the resulting complex is trigonal bipyramidal in shape.
