Hint: Chemical formula is a way to write a substance using the chemical symbol and number subscripts to mention the number of the atoms into that chemical compound. Acetophenone is an organic compound. The formula of Acetophenone is \[{C_6}{H_5}COC{H_3}\]. Dry distillation is a process where due to the heating of solid materials it produces gaseous products. In the dry distillation of calcium salt decarboxylation happens.
Complete step by step answer:
Ketones and aldehydes can be formed by the distillation of the calcium salt of carboxylic acid. In this distillation, calcium carbonate is formed by the decarboxylation from the carboxylic acid.
A general reaction equation of the distillation of calcium salt of carboxylic is shown below.
\[{(RCOO)_{2}}Ca + {(R'COO)_2}Ca\xrightarrow{{dry\;distillation}}2RCOR' + 2CaC{O_3}\]
\[{(RCOO)_{2}}Ca + {(HCOO)_2}Ca\xrightarrow{{dry\;distillation}}2RCOH + 2CaC{O_3}\]
Therefore, the equation of formation of acetophenone by this dry distillation of their calcium salt is shown below,
\[{({C_6}{H_5}COO)_{2}}Ca + {(C{H_3}COO)_2}Ca\xrightarrow{{dry\;distillation}}2{C_6}{H_5}COC{H_3} + 2CaC{O_3}\]
So, the correct option is C.
Note:
Ketonic decarboxylation (also known as ketonization) is one kind of organic reaction. In this reaction, a decarboxylation is converted from two equivalents of a carboxylic acid to asymmetric ketone by the application of heat with the expulsion of one equivalent of water and one equivalent of carbon dioxide. With two different carboxylic acids, the reaction is poor, this is because of poor selectivity. But when one of the acids is used in large excess then selectivity increases.
