    Acetic acid on decarboxylation gives:

    A)  Butane                        

    B)  Methane

    C)  Ethane                        

    D)  Propane

    Correct Answer: B

    Solution :

     Decarboxylation is a chemical reaction that re- moves a carboxyl group and releases carbon dioxide \[(C{{O}_{2}})\]. Usually, decarboxylation refers to a reaction of carboxylic acids (such as Acetic acid, \[C{{H}_{3}}C{{O}_{2}}H),\]removing a carbon atom from a carbon chain. The decarboxylation of acetic acid gives carbon dioxide and methane: \[C{{H}_{3}}C{{O}_{2}}H>C{{O}_{2}}+C{{H}_{4}}\]
