(a)
Interpretation:
The resonance forms of intermediates formed in solved problem
Concept introduction:
The resonance form of a substance related to the stability of the product, the more number of resonance forms increase the stability of a substance. The non-conjugated substances do not possess resonance structures. The presence of an alternation single and double bonds in a compound is known as conjugation.
(b)
Interpretation:
The mechanism for the acid-catalysed hydrolysis of ethyl formate is to be shown.
Concept introduction:
The synthesis of the compound relies upon the type of reactants and reagents that are used during the reactions. The energy of the product should be low because low energy of a compound increases the stability of a compound. The stability of a compound is the major factor that is responsible for the formation of a compound. The reagents perform numerous functions in reactions like proton abstraction, oxidation, reduction, catalysis, and dehydrogenation.

- Complete the mechanism of the reaction between benzaldehyde and dimethylamine in acid followed by introduction of a hydride reducing agent. Add any missing atoms, bonds, charges, nonbonding electron pairs, and curved arrows. Note that the use of a generic base B : represents another amine in solution that acts as a shuttle for the added acid. Step 1: Add curved arrows.

- Your answer is incorrect. Predict the relative rates of these reactions. That is, select 1 next to the reaction with the fastest rate, 2 next to the reaction with the next fastest rate, and so on. Note for advanced students: you may assume these reactions all take place in a polar aprotic solvent, like DMSO. Incorrect Your answer is incorrect. Predict the relative rates of these reactions.
