(a)
Interpretation:
The structure of the product is to be drawn for the given reaction from the given data.
Concept introduction:
The
Thus, both can react with the nucleophile depending, on the nature of the nucleophile and the regioselectivity of the reaction.
When the nucleophile adds to the carbonyl carbon, the reaction yields a

- (a) Draw the mechanism for the formation of both of the enols that can be formed from A (use acetic acid & AcOH as the source of the protons) (b) Draw the mechanism of reaction of this enol with bromine to give product Barrow_forwardFluorination of a benzene ring can be accomplished with Selectfluor, a reagent that contains a fluorine bonded to a positively charged nitrogen atom. Fluorination is a useful reaction because several common drugs, such as the cholesterol-lowering drug atorvastatin, contain a fluorine bonded to an aromatic ring. Assuming that fluorination is analogous to other examples of electrophilic aromatic substitution, draw a stepwise mechanism for the following reaction.arrow_forwarda) Draw all resonance forms of 3-hydroxybenzaldehyde and of the corresponding conjugate base. W hich conclusions can you draw for its acidity (pKa) in comparison to phenol?| b) Draw all resonance forms of 3-hydroxybenzaldehyde and of the corresponding conjugate base. Which conclusions can you draw for its acidity (pKa) in comparison to phenol and 3-hydroxybenzaldehyde? c) Discuss the relative acidities of 2-hydroxybenzaldehyd und 4-hydroxybenzaldehyd.arrow_forward
