Give a plausible explanation for the following statement: During the preparation of esters from a carboxylic acid and an alcohol in the presence of an acid catalyst, the water or the ester should be removed as soon as it is formed.
Options
- AThe accumulation of water in the reaction mixture can lead to side reactions or hydrolysis of the ester produc
- BThe presence of water can deactivate the acid catalyst, slowing down the esterification reaction. Removing wat
- CBecause when sufficient amounts of products are formed, the rate of forwarding reaction decreases and the reve
- DWater is a reactant in the esterification process, and its removal helps maintain the reaction at an optimal t
Correct answer
C. Because when sufficient amounts of products are formed, the rate of forwarding reaction decreases and the reve
Step-by-step solution
Correct Option is : (C) Because when sufficient amounts of products are formed, the rate of forwarding reaction decreases and the reverse reaction begins. To avoid this condition i.e., in order to shift the equilibrium in the forward direction, the concentration of products (ester and/or water) should be decreased. (Le-Chatelier's principle). So, water should be removed from time to time
