Answer:
option (e), dichloromethane, methene chloride
Explanation:
(a) [tex]CHCl_3[/tex]
Common name: chloroform
IUPAC name: one carbon atom, therefore, root word is meth.
Its is saturated compounds, so add ane after root word.
Three chlorine atoms are present.
Therefore, IUPAC name: Trichloromethane
(b) [tex]CCl_4[/tex]
Common name: Carbon tetrachloride
IUPAC name: one carbon atom, therefore, root word is meth.
Its is saturated compounds, so add ane after root word.
Four chlorine atoms are present, chlorine atoms are named as prefixes.
Therefore, IUPAC name: tetrachloromethane
(c) [tex]C_6H_5I[/tex]
Common name: Phenyl iodide
IUPAC name:
The given compound is an aryl halides. Aryl haildes are named as haloarenes. The prefix halo is placed before aromatic hydrocarbon. Here, prefix is iodo and aromatic hydrocarbon is benzene.
Therefore, IUPAC name of the compound is iodobenzene.
(d) [tex]CH_3Cl[/tex]
Common name: Methyl chloride
IUPAC name: one carbon atom, therefore, root word is meth.
Its is saturated compounds, so add ane after root word.
One chlorine atom is present.
Therefore, IUPAC name: chloromethane
(e) [tex]CH_2Cl_2[/tex]
Common name: Methylene chloride
IUPAC name: one carbon atom, therefore, root word is meth.
Its is saturated compounds, so add ane after root word.
Two chlorine atoms are present, chlorine atoms are named as prefixes.
Therefore, IUPAC name: dichloromethane.
Therefore, the correct option is option (e), dichloromethane, methene chloride
