Consider the following transformations: \[C{{H}_{3}}COOH\xrightarrow{CaC{{O}_{3}}}A\xrightarrow{heat}B\xrightarrow[NaOH]{{{I}_{2}}}C\] The molecular formula of C is

A) \[C{{H}_{3}}-\underset{I}{\overset{OH}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-C{{H}_{3}}\]   

B) \[IC{{H}_{2}}-COC{{H}_{3}}\]

C) \[CH{{I}_{3}}\]                       

D) \[C{{H}_{3}}I\]

Correct Answer: C

Solution :

[c]\[C{{H}_{3}}COOH+CaC{{O}_{3}}\to \underset{(A)}{\mathop{{{\left( C{{H}_{3}}COO \right)}_{2}}}}\,Ca\xrightarrow{Heat}\]
