The purpose of the SN1 and SN2 reactions are;
To study the effect of substrate structure and leaving groups on the sn1/sn2 reactions.
To compare the different mechanisms of nucleophilic substitution (SN) reactions.
<h3>What is nucleophilic reaction?</h3>
We know that in the reaction between an alkyl halide and a specie that has a high electron density, the reaction would involve the attack of a center that has a developing positive charge. The specie that attacks the center taht has the positive charge is called the nucleophile.
We know that the shape of the substrate alkyl halide affects the rate of the reaction or the nature of the nucleophilic reaction. The tertiary alkyl halides tend to undergo the reaction via the SN1 mechanism while the primary alkyl halides tend to undergo the reaction via the SN2 mechanim. The mechanism of the secondary alkyl halides would depend on the conditions of the reaction.
