Explain the sn2 mechanism
WebThe SN2 mechanism is a concerted mechanism because the nucleophile attacks the electrophile, at the same time we get loss of a leaving groups. There's only one step in … WebJan 23, 2024 · In the S N 2 reaction, the addition of the nucleophile and the departure of the leaving group occur in a concerted (taking place in a single step) manner, hence the name S N 2: substitution, nucleophilic, bimolecular. In the S N 2 reaction, the nucleophile approaches the carbon atom to which the leaving group is attached.

WebMar 16, 2024 · Que.1:- Explain SN1 and SN2 substitution reaction. Ans:- SN1 and SN2 are two common types of nucleophilic substitution reactions that occur in organic chemistry. SN1 (Substitution Nucleophilic Unimolecular) reaction is a two-step process where the leaving group departs from the substrate to form a carbocation intermediate, which is then ...
WebThe above S N 1 reaction takes place in three steps-. Formation of a tert-butyl carbocation by separation of a leaving group (Br −) from the carbon atom (this step is slow and reversible)-. (CH 3) 3C−Br (CH 3) 3C ++Br −. The carbocation reacts with the nucleophile. The intermediate is an oxonium ion (this reaction step is fast). Web4.) Here all alkyl halides are primary halides. So SN2 rate will only dependent on the leaving ability of halide ions. Size of I- > Br- > Cl- > F- So, leaving ability of I- is highest. Hence compound of option D will react most rapidly via SN2 …. …
