When a hydrogen atom of an alkane is replaced by halogens, they become an alkyl halide compound which can also be called haloalkanes. There are two types of reaction within the alkyl halides. When another atom replaces the halide ion, the reaction becomes a substitution reaction, and when the halide ion leaves with another atom or ion, it becomes an elimination reaction (Weldegirma, 2015). The substitution reaction can be divided into either electrophilic substitution or nucleophilic substitution. In the nucleophilic substitution, the substituent is electron rich and provides the electron pair for bonding with the substrate (Abdullah et al, 2015). It replaces a leaving group from the carbon atom and forms a new bond by using the lone pair of
