- What are the list of difference between SN1, SN2, E1, and E2? (such as the type of nucleophiles needed, the type of substrates, solvents etc.) When do we know when to use which mechanism? How do we use heat in an elimination reaction?How does the strength of the nucleophile affect an SN1 or SN2 mechanism?What is the strongest nucleophile, NH3, CH4, CH3O-, or H2O?
- From each pair, select the stronger nucleophile. Q.) CH3SH or CH3S-Reactions 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. (This is the rate-determining step of the reaction.)In an SN1 reaction, the nucleophile does not attack until the leaving group has left. (When the leaving group leaves, this is the rate-determining step of the reaction.)
