Concept explainers
(a)
Interpretation:
The detailed mechanism for the given reaction is to be drawn.
Concept introduction:
The acid anhydride can be prepared by reacting an ester and carboxylic acid in an acidic condition. The ester gets activated by protonation at carbonyl oxygen, and the carboxylic acid acts as a nucleophile.
(b)
Interpretation:
In general, the equilibrium of the given reaction favors reactants. However, if the ester used is replaced by another given ester, then equilibrium favors the products. It is to be explained why.

- Complete the mechanism for the hydrolysis shown by adding any missing bonds, charges, nonbonding electrons, and curved arrows.arrow_forwardwhich of the following reactions develops according to the nucleophilic substitution mechanism?arrow_forwardprovide the detailed arrow pushing mechanism for the given reactions. Do not skip any steparrow_forward
- Complete the curved arrow notation and include the structure of the missing organic intermediate for the following steps of a nucleophilic aromatic substitution via an addition–elimination mechanism.arrow_forwardDetermine the products of the following reactions, no reaction mechanism is necessary. In part b), where the question mark is, conditions can be proposed for any product of interest or that is feasible to obtain with the compound of the previous reaction.arrow_forwardDraw the mechanism arrows for the reaction between an acid chloride and an alcohol.arrow_forward
- Provide a mechanism for the intramolecular nucleophilic addition and elimination reaction shown here by providing the missing structures (including the final product) and curved arrows. The reaction resembles a Dieckmann condensation, except instead of two esters, the molecule contains an ester and a ketone. The ketone is more acidic and will be the nucleophile. Your structures should include all nonzero formal charges and lone pairs of electrons. When drawing the enolate place the negative charge on the carbon not the oxygen.arrow_forwardHello, I do not understand these questions and I am stuck. May I get help please please??
