Question

Match the procedural step to its purpose by dragging each step in the written procedure for the Fischer esterification of benzoic acid with methanol in the presence of mineral acid into the appropriate box. Purpose: Flat-bottomed flasks transfer heat in an uneven fashion, and may fracture if heated strongly. Procedure: Purpose: Methanol, which is used as a reagent and solvent, is flammable. Prodedue: Purpose: The unreacted carboxylic acid was neutralized under mild conditions. Procede: Purpose: Water needs to be removed before the liquid ester product is collected. Procedure:

Answer 1

Step-by-step explanation:

The task in this question is to match the right procedure to its purpose. It explains the procedure for the preparation of Fischer Esterification. Fischer Esterification Mechanism should incorporate the ceaseless expulsion of water from the framework or the use of a huge amount of excess alcohol since the general reaction is reversible. Fischer Esterification act as an organic reaction that is utilized to change over carboxylic acids within the sight of excess alcohol and a solid corrosive catalyst (acid) to give an ester as the eventual outcome.

Procedure Purpose

`\text{Flat bottomed flask transfer}\\ \\ \text{ heat in an uneven fashion and } \\ \\ \text{ may fracture if heated strongly}`
`\text{The reagents were added to a} \\ \\ \text{round bottom flask prior to the }\\ \\ \text{reaction being heated under reflux}`

`\text{Methanol which used as a reagent} \\ \\ \text{and solvent is flammable}`
`\text{The solution of benzoic acid and }\\ \\ \text{methanol was heated on steam bath}`

`\text{The unreacted carboxylic acid was} \\ \\ \text{neutralized under mild conditions}`
`\text{The reaction mixture was washed} \\ \\ \text{ with sodium bicarbonate solution}`

`\text{Water needs to be removed before the} \\ \\ \text{ liquid ester product was collected}`
`\text{Magnesium sulphate is added to the} \\ \\ \text{ dichloromethane layer before} \\ \\ \text{ the solvent is distilled off}`
