How do I perform this nucleophilic substitution reaction? Does this reaction have SN1 and SN2 occurring simultaneously? The nucleophile in this reaction is 4-tert-butyl phenol.
Identify the appropriate nucleophile and alkyl halide substrate to prepare this ether: Structure of the alkyl halide substrate? Structure of the nucleophile?
Are the following nucleophiles, electrophiles, they be both a nucleophile or electrophile, or neither? pyridine alkenes Hg+ (ex. Hg(OAc)2 CH3ONa PBr3
A student wanted to know whether the greater proximity of the nucleophile to the C-2 carbon in the transition state is what causes the 1,2-addition product to be formed faster when 1,3-butadiene reacts with HCl. Therefore, she decided to investigate the reaction of 2-methyl-1,3-cyclohexadiene with HCl. Her friend told her that she should use 1-methyl-1,3-cyclohexadiene instead. Should she follow her friend’s advice?
Why is Ch3coo- a better nucleophile than OH-?
explain why carbonyl compounds are so attractive to both nucleophiles and electrophiles
Why is the mechanism shown in Figure 28 not plausible? * A- The reagent does not have a good leaving group. B- Water is too weak a base for the reaction to occur. C- The structure of the haloalkane prevents the nucleophile from coming close to the alpha carbon atom. D- None of these statements are correct. E- All these statements are correct.
For each reaction below identify the electrophile and the nucleophile.
How does this mechanism work if OH- is a nucleophile? Would the electrons from the bond be transferred to oxygen after the nucleophile attacks the electrophile? Or is it a simultaneous process?
10. What is the name of the angle that a nucleophile approaches the carbon on the C=O bond? Borge-Dante Bürgi–Dunitz Baran-Daly Bunsen-Debye
Below is the equation for a nucleophilic substitution reaction and some experimental data. CH3CH2Br + CH3COO- ⇌ CH3CH2CO2CH3 + Br- ΔH=-75 kJ/mol Rate = k [CH3CH2Br][CH3COO-] Which reaction energy profile would be the best representative of the data provided?
The SN1 mechanism starts with the rate-determining step which is the dissociation of the alkyl halide into a carbocation and a halide ion. The next step is the rapid reaction of the carbocation intermediate with the nucleophile; this step completes the nucleophilic substitution stage. The step that follows the nucleophilic substitution is a fast acid-base reaction. The nucleophile now acts as a base to remove the proton from the oxonium ion from the previous step, to give the observed product. Draw a curved arrow mechanism for the reaction, adding steps as necessary. Be sure to include all nonzero formal charges.
