When naming the molecular compound SO_2, which prefix should be used for the oxygen atom?
A
mono-
B
tetra-
C
di-
D
tri-
0 Comments
Verified step by step guidance1
Understand that molecular compounds are named using prefixes to indicate the number of atoms of each element present in the molecule.
Recall the common prefixes used in molecular compound nomenclature: mono- (1), di- (2), tri- (3), tetra- (4), etc.
Identify the number of oxygen atoms in SO_2, which is 2.
Match the number of oxygen atoms to the correct prefix, which is 'di-' for 2 atoms.
Therefore, the prefix 'di-' should be used for the oxygen atom in SO_2.
