Question 11 • Chemistry

The IUPAC name for NF sub 3 should have which of these?

Answer
A
the prefix “tri” before fluoride
B
the Roman numeral (III) after nitrogen
C
the Roman numeral (III) after fluoride
D
the prefix “tri” before nitrogen

Explanation

NF₃ is a molecular compound made of two nonmetals, so its name uses prefixes to show how many atoms of each element are present. There are three fluorine atoms, giving the name nitrogen trifluoride; “tri” comes before fluoride. The name does not use a Roman numeral for this compound.
