Question 2 3 pts
Which of the following names is correctly matched with the corresponding chemical formula (as
outlined in class)?
*Note: All numbers should be considered as subscripts!
O HCN - formonitrile
NH3 - nitrogen trihydride
HBr = monohydrogen monobromide
SiF4 = silicon tetrafluorine

NH3 - nitrogen trihydride

Explanation:

In attempting to answer this question we should keep certain things in mind. We should remember that the subscripts show the number of atoms of each element present in the compound and we do not use the prefix "mono" twice in naming a binary compound.

The prefixes "mono", "di" etc are used when the central atom in the compound can form more than one compound with the same atom; E.g carbon monoxide and carbon dioxide. Hence the description, monohydrogen monobromide is incorrect.

Also, SiF4 is silicon tetrafluoride and not silicon tetrafluorine.

Hence, only NH3 was correctly described as nitrogen trihydride.
