Which of the following is an example of SN2 reaction? (a) CH Br OH CH OH Br -> (b) CH3 C CH3 CH3 Cl - Cl- CH3 C CH3 CH3 + Cl CH3 C CH3 CH3 + OH CH3 C CH3 CH3 OH H2O .. .. Θ Me-O-CH -Cl Me-O-CH Cl Me-O=CH -> (c) H O CH CH OH CH CH ->

N S 2 reaction means nucleophilic substitution bi molecular reaction. This reaction takes place when the leaving group is attached to the primary carbon atom. Let us look at each option: Option A: - - 3 3 CH Br+OH CH OH+Br -> Here in this reaction, the Br is replaced by the OH group which means it is a substitution reaction and the attacking agent is the - OH group which is a nucleophile. This means that this is a nucleophilic substitution reaction. Now, the leaving group i.e. Br is attached to a primary carbon which means that this reaction will be nucleophilic substitution bi-molecular reac
