WebDec 18, 2024 · Note : When does SN2 attack occur. Let's analyse this and you will get your answer in end. First of all the steric hindrance around the carbon atom should be least i.e if RX is 1° (primary) then SN2 attack always (mostly) occurs. If RX is 3° (tertiary) then SN1 attack always (mostly) occurs, as steric hindrance is very high.

WebWe can summarize the behavior of tertiary haloalkanes as follows: 1. If the nucleophile is a weak base, tertiary haloalkanes react by either an S N 1 or E1 mechanism, and the S N 1 reaction is favored. 2. If the nucleophile is a strong base, tertiary haloalkanes react by either an S N 1 or E2 mechanism, and the E2 reaction is favored.

SN1 vs SN2. E1, E2, SN1, or SN2? [with printable chart]

WebIt isn't actually a strong nucleophile, but the substrate is primary in that reaction, so SN2 is still favored over SN1. Determining what kind of substrate (methyl, primary, secondary, or tertiary) you have takes precedence over what type of nucleophile and solvent you have when you're distinguishing whether it'll be SN1 or SN2.
