Question

Which of the following is not a name of a valid chemical formula?
Select one:
a. carbon chloride
b. nitrogen monoxide
c. copper (II) carbonate
d. chloric acid

Answer 1

Among the compounds given, the one that is not valid is a. carbon chloride. a compound composed of non-metals should have prefixes that is related to the number of atoms of the elements present. In this case, the other cmopounds are considered valid but not A 

Answer 2

The correct answer is: Option (a) Carbon Chloride

Explanation:
Carbon has four valence electrons; therefore, it would require 4 more electrons to become stable. Chlorine, however, has seven (7) valence electrons. So it would require only one electron to become stable. In this case, as in the name, carbon chloride, the word chloride refers to the compound that is stable, which in this case cannot be possible (as carbon requires 4 electrons, and chlorine only has 7). If chlorine had 4 valence electrons, then it would be possible. Hence, the correct option is (a) Carbon Chloride.
