Question

The IUPAC name of the following compound is benzyl chloride:

A. True
B. False

Answer 1

IUPAC” stands for International Union of Pure and Applied Chemistry which gives some rules for the nomenclature of the chemical compounds which is the same everywhere, because sometimes one compound may have many names and people get confused. That’s why universally we use IUPAC names instead of regular names.

Step by step answer: Complete step by step solution: The IUPAC name of given compound is not benzyl chloride and reason is as follows:

Because the formula of benzyl chloride is ${C_6}{H_5}C{H_2}Cl,$ where ${C_6}{H_5}C{H_2} -$ represents the benzyl part and $C{l^ - }$ represents the chloride part.

But in the given diagram the benzyl part is not present in place of that part benzoyl is present whose formula represents ${C_6}{H_5}CO$.

So, from the above discussion it is clear that the IUPAC name of given compound is false; that is it is not benzyl chloride.

Additional information: Benzoyl chloride is also known as benzene carbonyl chloride because with benzene ring carbonyl group is attached, its molecular formula is written as ${C_7}{H_5}COCl$.
Benzoyl chloride is widely used in many chemical reactions as for the preparation of dyes, perfumes, resins, drugs, etc.
Molecular formula of benzyl chloride is written as ${C_7}{H_7}Cl$ and it is also widely used in the preparation of dyes, drugs, lubricants, etc.

Note: In this question many of you may get confuse in the IUPAC name as there is not much difference in the structure and name of Benzoyl chloride & benzyl chloride. So, always keep in mind the chemical formula of benzyl and benzoyl for ignoring any kind of mistake.
