What is the result when glycerol is heated with oxalic acid?

1. CH2OH—CHOH—CH2OH transforms into CH2OH—CHOH—CH2COOH
2. CH2OH—CHOH—CH2OH converts to CH2OH—CHOH—CH2COOH along with H2O
3. CH2OH—CHOH—CH2OH changes to CH2OH—CHOH—CH2COOH and CO2 is released
4. CH2OH—CHOH—CH2OH reacts to form CH2OH—CHOH—CH2COOH and HCOOH

Correct answer: CH2OH—CHOH—CH2OH reacts to form CH2OH—CHOH—CH2COOH and HCOOH

Solution

When glycerol is heated with oxalic acid, formic acid (HCOOH) is released along with the formation of glyceric acid (CH2OH—CHOH—CH2COOH). This is a characteristic reaction of glycerol with oxalic acid.
