Vedclass · Answer

(B) For a chemical reaction to occur,reactant molecules must collide with sufficient energy (activation energy) and in the proper orientation (steric factor).An excellent example is the $S_N2$ reaction between bromomethane $(CH_3Br)$ and the hydroxide ion $(OH^-)$.In this reaction,the $OH^-$ ion must attack the carbon atom from the side opposite to the $Br^-$ atom (backside attack).If the $OH^-$ ion approaches from the same side as the $Br^-$ atom,the repulsion between the negative charges prevents the reaction.Thus,the proper orientation is essential for the formation of methanol $(CH_3OH)$.
