Question

how how you would synthesize the following esters from appropriate acyl chloridesand alcohols.(a) ethyl propionate (c) benzyl benzoate (e) tert-butyl acetate(b) phenyl 3-methyl hexanoate(d) cyclopropyl cyclohexanecarboxylate (f) diallyl succinate

Answer 1

Esters can be synthesized by reacting acyl chlorides with alcohols. Condensation reactions involving these reactants produce various esters like ethyl propionate, benzyl benzoate, and tert-butyl acetate, among others.

Step-by-step explanation:

Esther synthesis typically involves the reaction of an alcohol with an acyl chloride under suitable conditions. Here, we will discuss the synthesis of various esters from specific acyl chlorides and alcohols:

• Ethyl propionate: React ethanol (CH3CH2OH) with propanoyl chloride (C2H5COCl).
• Benzyl benzoate: React benzyl alcohol (C6H5CH2OH) with benzoyl chloride (C6H5COCl).
• Tert-butyl acetate: React tert-butanol ((CH3)3COH) with acetyl chloride (CH3COCl).
• Phenyl 3-methyl hexanoate: React phenol (C6H5OH) with 3-methylhexanoyl chloride (C7H13COCl).
• Cyclopropyl cyclohexanecarboxylate: React cyclopropyl alcohol (C3H5OH) with cyclohexanecarbonyl chloride (C6H11COCl).
• Diallyl succinate: React allyl alcohol (CH2=CHCH2OH) with succinyl chloride (HOOCCH2CH2COCl).

Each of these reactions involves the nucleophilic attack of the alcohol on the acyl chloride to form the corresponding ester and Hydrochloric Acid (HCl) as a byproduct. This reaction type is a kind of condensation reaction, specifically known as the Fischer esterification when involving carboxylic acids.
