Reactivity order of sn2 reaction

WebMay 10, 2024 · The order of reactivities of alkyl halides towards the SN 2 reaction is: The reaction is faster when the alkyl group of the substance is methyl. When the hydrogen atoms of methyl group are replaced by bulkier alkyl groups, the increased crowding around central atom hinders the attack of nucleophile. This is called steric hindrance. WebJul 14, 2024 · SN2 Reaction This reaction follows second order kinetics and the rate of reaction depends upon both haloalkane and participating nucleophile. Hence, this reaction is known as substitution nucleophilic …

8.3. Factors affecting rate of nucleophilic substitution reactions

WebS N2 reactivity increases if the carbocation formed is least stable. So, the cations formed are: (II) is more stable due to inductive effect of 4-methyl groups at meta-position. (III) is stable due inductive effect of 2-methyl group at meta (i) is least stable. So (i) has more reactivity towards S N2 ⇒ Ans :- i > iii > ii ⇒ Ans :- C WebNucleophile. For an S N 2 reaction, nucleophile are one of the rate-determining factors; therefore, strong nucleophiles help to speed up S N 2 reactions. The relative strength of a nucleophile is called nucleophilicity. The nucleophilicity of a nucleophile is measured in terms of the relative rate of its S N 2 reaction with the same substrate.
