• # question_answer Which of the following compounds is formed when ethanol reacts with acetic acid in the presence of concentrated${{H}_{2}}S{{O}_{4}}?$ A) ${{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}$            B) $C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}$          C) $C{{H}_{3}}C{{H}_{2}}CHO$D)   $C{{H}_{3}}OC{{H}_{3}}$

Esterification ${{C}_{2}}{{H}_{5}}OH+C{{H}_{3}}COOH\xrightarrow{conc.\,{{H}_{2}}S{{O}_{4}}}$ $C{{H}_{3}}COO{{C}_{2}}{{H}_{5}}+{{H}_{2}}O$ Hence, the correct option is (b).
