Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The removal of carbon from a molecule in the form of carbon dioxide is known as
A
decarboxylation
B
dehydrogenation
C
phosphorylation
D
oxidation
Explanation: 

Detailed explanation-1: -Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO2). Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain.

Detailed explanation-2: -Loss of carbon dioxide is called decarboxylation. Esters or carboxylic acids with a carbonyl group at the 3-(or b-) position readily undergo thermal decarboxylation. Decarboxylation was first encountered in Chapter 19 for carboxylic acids (review). The reactive species is the carboxylic acid or the carboxylate anion.

Detailed explanation-3: -Carbon dioxide removal (CDR), also known as negative CO 2 emissions, is a process in which carbon dioxide gas (CO 2) is removed from the atmosphere and sequestered for long periods of time.

Detailed explanation-4: -Example: CH3−C−ONa+NaOHCaO CH4+Na2CO3.

Detailed explanation-5: -: the removal or elimination of carboxyl from a molecule.
