Here are the essential concepts you must grasp in order to answer the question correctly.
Nucleophiles
Nucleophiles are species that donate an electron pair to form a chemical bond in a reaction. They are typically negatively charged or neutral molecules with lone pairs of electrons. In organic synthesis, nucleophiles attack electrophilic centers, facilitating various reactions such as nucleophilic substitutions or additions.

Ester Synthesis
Ester synthesis often involves the reaction of an alcohol with a carboxylic acid or its derivatives. In this context, methyl acetate can be transformed into ethyl acetate through nucleophilic substitution, where a neutral nucleophile, such as ethanol, attacks the carbonyl carbon of methyl acetate, displacing the methanol group.

Reactivity of Acetates
Acetates, like methyl acetate, are relatively reactive due to the presence of the carbonyl group, which is electrophilic. This reactivity allows them to undergo nucleophilic attack by alcohols or other nucleophiles, leading to the formation of new esters. Understanding the reactivity of acetates is crucial for predicting the products of nucleophilic substitution reactions.
