WebDec 31, 2012 · The “big barrier” to the SN2 reaction is steric hindrance. That is why the rate of SN2 reactions is 1° > 2° > 3°. The nucleophile cannot squeeze in between the alkyl groups of a 3° substrate to attack the backside of the α carbon. The effect is even worse if the nucleophile itself is bulky. WebThe lower on the periodic table the halogen is, the faster the rate will be. This is because they form better leaving groups. A good leaving group can be though of as the conjugate of a strong acid; in the case of halogens, the lower on the periodic table the halogen is the more acidic it will be, as it has a larger atomic radius to distribute its negative charge. chitty chitty bang bang history
