Interpretation Introduction

(a)

Interpretation: The products formed by the treatment of benzoic anhydride $\left[{\left({\text{C}}_{\text{6}}{\text{H}}_{\text{5}}\text{CO}\right)}_{\text{2}}\text{O}\right]$ with ${\text{H}}_{\text{2}}\text{O}$ are to be drawn.

Concept introduction: Anhydrides involve two carbonyl groups. The nucleophilic substitution reaction of anhydride involves the attack of nucleophilic at one carbonyl group, which causes the second carbonyl group to be the part of leaving group.

Interpretation Introduction

(b)

Interpretation: The products formed by the treatment of benzoic anhydride $\left[{\left({\text{C}}_{\text{6}}{\text{H}}_{\text{5}}\text{CO}\right)}_{\text{2}}\text{O}\right]$ with ${\text{CH}}_{\text{3}}\text{OH}$ are to be drawn.

Concept introduction: Anhydrides involve two carbonyl groups. The nucleophilic substitution reaction of anhydride involves the attack of nucleophilic at one carbonyl group, which causes the second carbonyl group to be the part of leaving group.

Interpretation Introduction

(c)

Interpretation: The products formed by the treatment of benzoic anhydride $\left[{\left({\text{C}}_{\text{6}}{\text{H}}_{\text{5}}\text{CO}\right)}_{\text{2}}\text{O}\right]$ with ${\text{NH}}_{\text{3}}$ (excess) are to be drawn.

Concept introduction: Anhydrides involve two carbonyl groups. The nucleophilic substitution reaction of anhydride involves the attack of nucleophilic at one carbonyl group, which causes the second carbonyl group to be the part of leaving group.

Interpretation Introduction

(d)

Interpretation: The products formed by the treatment of benzoic anhydride $\left[{\left({\text{C}}_{\text{6}}{\text{H}}_{\text{5}}\text{CO}\right)}_{\text{2}}\text{O}\right]$ with ${\left({\text{CH}}_{\text{3}}\right)}_{\text{2}}\text{NH}$ (excess) are to be drawn.
