Question
Which of the following reagents can be used to convert CH3CH2COOH into CH3CH2COCl?Select answer from the options belowSOCl2 Cl2NaClHCl
Solution
The reagent that can be used to convert CH3CH2COOH (propanoic acid) into CH3CH2COCl (propanoyl chloride) is SOCl2 (thionyl chloride).
Here's the step by step process:
- The carboxylic acid (CH3CH2COOH) reacts with thionyl chloride (SOCl2).
- The oxygen in the carboxylic acid forms a bond with the sulfur in thionyl chloride, and the hydrogen in the carboxylic acid forms a bond with the chlorine in thionyl chloride. This results in the formation of sulfur dioxide (SO2) and hydrogen chloride (HCl), which are both gases and will leave the reaction.
- The remaining chlorine atom in thionyl chloride forms a bond with the carbon in the carboxylic acid, replacing the OH group and forming the acyl chloride (CH3CH2COCl).
So, the correct answer is SOCl2.
