$0.2\;mol$ of an alcohol is esterified with $0.2\;moles$ of ethanoic acid $A$ . After reaching equilibrium, the remaining acid is isolated and titrated by $40.0\;mL$ of $2.0\;M\;NaOH$ to the equivalence point. It is asked 1) the percentage of esterified compound $A$. 2) the class of the ester which is formed knowing that the esterification limit for an equimolar mixture of acetic acid - alcohol is about $67\%$ if the alcohol is primary, $60\%$ if the alcohol is secondary and $5\%$ if alcohol is tertiary.
