Final answer:
The product of the reaction between acetic acid and methanol in acidic conditions and heat is methyl acetate and water.
Step-by-step explanation:
The student is asking about the product formed when acetic acid (CH3-C(=O)-OH) reacts with methanol (CH3-OH) in the presence of acid (H+) and heat. The reaction between a carboxylic acid and an alcohol in the presence of an acid catalyst is known as esterification. The product of such a reaction is an ester and water.
In this particular case, the acetic acid will react with the methanol to form methyl acetate (CH3-C(=O)-OCH3) and water (H2O). The reaction can be written as:
CH3C(=O)OH + CH3OH → (CH3C(=O)OCH3) + H2O
