Step-by-step solution

Definition of decarboxylation

Decarboxylation is a process of removal of the carbonyl group that in turn removes carbon dioxide from any structure. The process is entropically favorable due to the release of gas.

Cause of decarboxylation

Decarboxylation occurs when a carboxylic group (-COOH) is bonded to the - carbon of another carbonyl group or a structure where a $\beta$-keto acid is present. After the removal of carbon dioxide, the negative charge formed in the adjacent carbonyl group is stabilized by the -I effect of the carbonyl group.

This structure is stabilized by $\alpha$- carboxylic group to undergo decarboxylation.

Representation of a structure where decarboxylation is not possible.

This structure is non-stabilized to undergo decarboxylation.

This structure is stabilized by $\beta$-keto to undergo decarboxylation.

Representation of a structure where decarboxylation is not possible.

This structure is non-stabilized to undergo decarboxylation.

Hence, based on the explanations, the compounds that readily lose CO₂ when heated are shown below

Molecules that undergo decarboxylation.
