B
monoiodine oxide
C

Verified step by step guidance1
Identify the elements present in the compound IO5. The compound consists of iodine (I) and oxygen (O).
Determine the number of atoms of each element in the compound. The subscript '5' indicates there are five oxygen atoms.
Apply the rules for naming binary compounds. For non-metal compounds, use prefixes to indicate the number of atoms. The prefix 'penta-' is used for five.
Combine the element names with the appropriate prefixes. Iodine remains as 'iodine', and oxygen with five atoms becomes 'pentoxide'.
Construct the systematic name by combining the element name and the prefix-modified second element: 'iodine pentoxide'.
