Br tBuO H3C H3C CH2 H2 Alkyl halides undergo nucleophilic substitution and elimination reactions. When the kinetics of the reaction are measured, if the rate of the reaction is found alkyl halide the reaction is second order. The substitution reaction is thus termed SN2, and the elimination reaction is be dependent upon the concentration of the nucleophile as well as the termed E2. These reactions are bimolecular and take place in a single step. In the SN2 reaction, the nucleophile attacks the a-carbon from the backside and displaces the leaving group with an inversion of configuration occurring at the carbon. In the E2 elimination reaction, strong base removes an acidic hydrogen from the B-carbon and an alkene is formed as the leaving group is expelled from the a-carbon. This elimination follows Zaitsev's rule whereby the more substituted alkene is generally formed. In E2 elimination, both the B-hydrogen and the leaving group must be oriented anti to each other. The same reaction…

2. Draw the structures and explain why CH3CH₂O and CH3CO₂ are good nucleophiles but CH3SO3, water, and alcohols (R-OH) are poor nucleophiles. Propose a 'cutoff' for the amount of negative charge needed to be a good nucleophile. CH3CH₂O CH3CO₂ CH3SO3 H₂O CH₂OH

What is the rate-determining step in the mechanism of an electrophilic substitution reaction of benzene? Select one: OA. Attachment of the electrophile to benzene ring. OB. Bonding of catalyst to electrophile precursor. O C. Reformation of acid catalyst. OD. Formation of the electrophile. OE. Loss of H+ ion form arenium ion intermediate to reform aromatic ring.

Label the nucleophile and the electrophile, the nucleophilic atom and the electrophilic atom.

please do the mechanism. Identify which one is the nucleophile/electrophile. Name the reaction as well.  Discuss the stereochemistry so why the dash bond go to wedged- due to inversion? Why is PPh3 used for selectivity ? Please answer all of my questions.
