Question

among the given reactions which is the best example of SN² REACTION.
​

Answer 1

Answer:

(3)

Explanation:

SN2 requires strong nucleophile.

CH3O- in DMSO is a strong nucleophile

Answer 2

Option 4 is the correct and the best example of SN² reaction.

• SN² reactions are a part of organic chemistry and if one bond is broken another is synchronously formed means SN² is a type of nucleophilic substitution reaction mechanism.
• Generally, only 1-degree alkyl halides go through SN² reactions and also the ones with less bulky halogen tend to react faster as less the bulkiness more is the reactivity towards SN² reaction.
• Therefore, option 4 is the correct and the best example of SN² reaction.
