The alkane formed on heating sodium butanoate with sodalime is

Options

  1. AMethane
  2. BEthane
  3. CPropane
  4. DButane

Correct answer

C. Propane

Step-by-step solution

The alkane formed on heating sodium butanoate with sodalime is propane. In this reaction , the product contains one carbon atom less than the carboxylic acid. This process of elimination of carbon dioxide from a carboxylic acid is known as decarboxylation.
