WebAug 2, 2014 · An S N 1 reaction on the first molecule with the phenyl substituent would yield a primary carbocation, yes, but this primary carbocation is also benzylic, and can be stabilized through resonance. WebSN1 versus SN2 Reactions. Whether an alkyl halide will undergo an S N 1 or an S N 2 reaction depends upon a number of factors. Some of the more common factors include the natures of the carbon skeleton, the solvent, the leaving group, and the nature of the nucleophile. Only those molecules that form extremely stable cations undergo S N 1 ...

As noted by a comment, methanol is not a very good nucleophile, and SN2 reactions require a … WebSep 24, 2024 · 1) For Reaction A, the rate law is rate = k[CH 3 I][CH 3 S-]. Therefore, if the concentration of the nucleophile, CH 3 S-, is doubled and the concentration of the alkyl halide remains the same, then the reaction rate will double. For Reaction B, the rate law is …

Allyl halides are also reactive to S N 2' reactions, … WebDec 25, 2024 · Naturally, if X is a very poor leaving group — e.g. O T B S — the attack on the carbonyl will dominate this way or that. To sum up: The reaction rate is increased because the σ ∗ ( C − X) orbital and the π ∗ ( C = …
WebYes, there is always a mixture of R and S products when an SN1 reaction occurs. It happens because the carbocation is planar and can be attacked from either side to form an R,S mixture. They are not always formed in equal amounts, however.
WebAs Hammond’s Postulate tells us, this stable carbocation will form fairly quickly, making the SN1 reaction viable even though benzyl chloride is formally a primary alkyl halide.
