Question

The IUPAC name of the $\text{CC}{{\text{l}}_{\text{4}}}$ is:
A. pyrene
B. Carbon tetrachloride
C. tetrachlorocarbon
D. tetrachloromethane

Answer 1

Hint: We can find the IUPAC name of $\text{CC}{{\text{l}}_{\text{4}}}$ from the structure, with the help of nomenclature. Once we are able to name the compound from the structure, we can compare it with the options provided.

Complete step-by-step answer:
Below is the structure of $\text{CC}{{\text{l}}_{\text{4}}}$.

From the structure we can see that carbon is the central atom. There are 4 chlorine atoms as the functional groups of the central atom. So, in order to name the compound, we need to consider the position of the chloride atoms, which are 1,1,1,1.
So the IUPAC name of the compound is 1,1,1,1 - tetracholomethane. Here the name is signed as per the position. Here,
Tetra signifies the secondary prefix for four carbon atoms.
Chloro signifies the primary prefix for chlorine.
Meth signifies the root word for carbon number.
Ane signifies the primary suffix for alkane
Therefore, the name is 1,1,1,1 - tetrachloromethane, which can be written as tetrachloromethane. So the correct option is Option D.
