The molecule structure is shown in the attachment.
a) benzoic acid and ethanol
Explanation: Esterification is a chemical reaction between carboxilic acids and alcohols to produce esters, which is a molecule containing a hydrocarbon of some kind. For example, in general:
R - COOH + R'OH ⇄ R-COOR' + H₂O
So, from this equation, we noticed that hydrogen from the carboxilic acid dissociates to form water with the -OH from the alcohol.
The figure in the attachment shows an union of a benzoic acid (C₆H₅CO₂) and an alcohol containing 2 carbons, i.e., ethanol (CH₂CH₃), then to produce C₆H₅CO₂CH₂CH₃ is necessary a benzoic acid and ethanol.
