WebReactions are impacted by various factors that depend on the mechanism of the reaction.Some of the variables for substitution reactions are: • strength of the nucleophile • concentration of the nucleophile • leaving group ability (i.e., is it a “bad” or a “good” leaving group?In an SN2 reaction, the nucleophile forces the leaving group to leave. WebA long, straight wire carries a current of $5.20 \mathrm{~A}$. An electron is traveling in the vicinity of the wire. At the instant when the electron is $4.50 \mathrm{~cm}$ from the wire and traveling with a speed of $6.00 \times 10^4 \mathrm{~m} / \mathrm{s}$ directly toward the wire, what are the magnitude and direction (relative to the direction of the current) of …
WebSep 18, 2024 · Improve this question. As per the theory of chemistry, we say that unstable carbocations undergo S N 2 reactions as it involves strong nucleophile. As a consequence, it does not lead to the formation of reaction intermediate, i.e. a carbocation. Similarly, in stable carbocations undergo S N 1 reaction by substitution of a weak …
