3. Why is it necessary to use prefixes in the names of covalent compounds? In covalent compounds, the neutral non-metal atoms involved can combine in a variety of ratios, producing several different compounds (containing the same elements). Thus prefixes are needed in their names to differentiate between these compounds, by indicating the number of atoms of each non-metal atom found in them. 4. In what cases do we not use prefixes in the names of covalent compounds? The prefix "mono" is dropped from the name of the first element when there is only one atom of that element present. Also, no prefixes at all are used in the names of covalent compounds containing hydrogen.
