Expert Answer
In the above reaction the SN2 reaction mechanism is follows. In which the reaction site is attacked the from backside by the nucleophile I- to get the final product.
Because of backside attack the configuration is inverted and we get inverted product.
More information related to SN2 reaction:
Sn2 Reactions
* The SN2 reaction is also known as bimolecular nucleophilic substitution.
* It is a type of nucleophilic substitution, where a lone pair from a nucleophile attacks an electron deficient electrophilic center and bonds with it, leaving behind what may be called as a leaving group. So, the leaving group is replaced by the incoming group in the very first step.
* Such reactions are named as bimolecular nucleophilic substitution because two reacting species are involved in this process. It is a slow and rate-determining step.
* The SN2 reaction is known as the interchange mechanism among inorganic chemists.
