Question

Furfuran on decarboxylation at 673 K gives

Answer 1

Explanation

A carboxyl group is removed during the chemical reaction of decarboxylation, which also produces carbon dioxide (CO2). Decarboxylation typically refers to the removal of a carbon atom from a carbon chain through a reaction of carboxylic acids. Carboxylation, or the addition of CO2 to a molecule, is the opposite reaction and the first chemical step in photosynthesis. The term "decarboxylase" refers to an enzyme that catalyses decarboxylations.

Furan can be produced in the lab from furfural by first being oxidised to furan 2 carboxylic acid, then decarboxylated.

It can also be produced directly through the thermal degradation of cellulosic materials, particularly pine wood, that contain pentose.
