Questions & Step-by-Step Solutions

Which reagent is commonly used to convert a carboxylic acid to an acid chloride?
Correct Answer: Thionyl chloride (SOCl2)
  • Step 1: Understand that a carboxylic acid is a type of organic compound that contains a carboxyl group (-COOH).
  • Step 2: Know that an acid chloride is a compound derived from a carboxylic acid by replacing the -OH group with a -Cl group.
  • Step 3: Learn that there are several reagents that can be used to convert carboxylic acids to acid chlorides.
  • Step 4: Recognize that common reagents include thionyl chloride (SOCl2), oxalyl chloride (COCl)2, and phosphorus pentachloride (PCl5).
  • Step 5: Conclude that all of the listed reagents can effectively perform this conversion.
