Question

RCOOR' can be prepared by :

• A. esterification of RCOOH
• B. esterification of ${\left(RCO\right)}_{2}O$
• C. Baeyer $-$ Villiger oxidation of RCOR' with peroxy acid
• D. reaction of RCOCl with R'OH

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A esterification of RCOOH
B esterification of ${\left(RCO\right)}_{2}O$
C Baeyer $-$ Villiger oxidation of RCOR' with peroxy acid
D reaction of RCOCl with R'OH

When a carboxylic acid (RCOOH) or an acid anhydride (RCOOCOR) is esterified with an alcohol (R'OH), an ester (RCOOR') is obtained.
When a ketone (RCOR') is treated with peroxy acid (R"COOOH), an ester (RCOOR') is obtained. This reaction is known as Baeyer Villiger oxidation.
When an acid chloride (RCOCl) reacts with an alcohol (R'OH), an ester (RCOOR') is obtained.
