Hint: The name of ${{C}_{6}}{{H}_{5}}COCl$other than IUPAC is benzenecarbonyl chloride. And the IUPAC name of ${{C}_{6}}{{H}_{5}}COCl$is similar to benzenecarbonyl chloride. It is an organic compound.
Complete step by step answer:
The IUPAC name of ${{C}_{6}}{{H}_{5}}COCl$is Benzoyl chloride. The other name of benzoyl chloride is benzene carbonyl chloride. It is an organic compound or specifically saying it is an organochlorine compound. It has a very irritating odor. It is a colorless, fuming liquid at room temperature.
The peroxides which are used in many chemical reactions, the polymerization reaction is produced from benzoyl chloride. Other than the production of peroxides, it is used for the preparation of resins, perfumes, dyes, and pharmaceuticals.
The structure of benzoyl chloride is given below:
The benzoyl chloride can be produced by two reactions:
(i)- Action of water on benzotrichloride. The reaction is given below:
${{C}_{6}}{{H}_{5}}CC{{l}_{3}}+{{H}_{2}}O\to {{C}_{6}}{{H}_{5}}COCl+2HCl$
(ii)- Action of benzoic acid on benzotrichloride. The reaction is given below:
${{C}_{6}}{{H}_{5}}CC{{l}_{3}}+{{C}_{6}}{{H}_{5}}C{{O}_{2}}H\to 2{{C}_{6}}{{H}_{5}}COCl+HCl$
Benzoyl chloride produces hydrochloric acid and benzoic acid when it reacts with water. The reaction is given below:
${{C}_{6}}{{H}_{5}}COCl+{{H}_{2}}O\to {{C}_{6}}{{H}_{5}}C{{O}_{2}}H+HCl$
Benzoyl chloride is a member of group acyl chloride. As it is a member of acyl chloride when it reacts with alcohol, it produces esters. And when it reacts with amine it forms amide.
Industrially benzoyl chloride is converted into benzoyl peroxide which is used as a common reagent in polymer chemistry.
So, the correct answer is an option (a)- Benzoyl chloride.
Note: You may get between the benzene chloro ketone or chlorophenyl ketone because there is a presence of ketone group in ${{C}_{6}}{{H}_{5}}COCl$. It belongs to acyl chloride, hence, its name is benzoyl chloride.
