Chapter 12, Problem 4Q

Interpretation Introduction

Interpretation:

Thelimiting reagent, excess reagent and the excess number of moles of excess reagent in the formation of ester from acetic acid and isopentyl alcohol needs to be determined.

Concept Introduction:

Ester is an organic compound with the general formula RCOOR. It can be formed by the reaction of carboxylic acid with alcohol in the presence of acidic medium. This reaction is called as esterification reaction. The esterification reaction of acetic acid with isopentyl alcohol forms isopentyl acetate. The chemical equation can be written as:

  ${\text{CH}}_{\text{3}}{\text{COOH + (CH}}_{\text{3}}{\text{)}}_{\text{2}}{\text{-CH}}_{\text{2}}{\text{-CH}}_{\text{2}}\text{-OH}\rightleftarrows {\text{CH}}_{\text{3}}{\text{COOCH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH(CH}}_{\text{3}}{\text{)}}_{\text{2}}{\text{+H}}_{\text{2}}\text{O}$
