Question

The IUPAC name of chloropicrin is:
A.Trichloronitromethane
B.1, 1, 1 – trichloro – 2 – methyl – 2 - propanol
C.3 - hydroxybutanal
D.2, 2, 2 - trichloroethanal

Answer 1

To answer this question, you should recall the concept of IUPAC nomenclature of IUPAC compounds. The IUPAC system rose to the necessity for a systematic approach due to the sheer quantity of discoveries of organic compounds which made the vernacular nomenclature of organic compounds highly inconvenient. We shall write the formula of chloropicrin and name the compound using IUPAC nomenclature procedure.

Complete step by step answer:
A set of rules has been formulated by IUPAC for a systematic approach for the nomenclature of organic compounds which has been revised from time to time. Any IUPAC name of the given organic compound consists of three parts of the name which are: parent name, prefix and suffix.
Chloropicrin is a derivative of the nitro compound where all the hydrogens are substituted and replaced by chlorines. Chloropicrin has a chemical formula of $CC{l_3}N{O_2}$ . It has a single carbon atom and thus, the parent chain is methane. It has 3 chlorine atoms and 1 nitro group attached to it.
The IUPAC name of chloropicrin $CC{l_3}N{O_2}$ ​ is trichloronitromethane.

Hence, the correct option is option A.

Note:
It causes inflammation of the eyes, nose and throat, and significant injuries to the upper and lower respiratory tract. In agricultural farming, the chloropicrin is injected into the soil before planting a crop to fumigate soil.
