As Ava was writing the name of CO₂ she decided that its name was monocarbon dioxide. This is incorrect. What did Ava do wrong?

• Ava did nothing wrong. The correct name of CO₂ is monocarbon dioxide.

• Ava added the pre-fix "mono" to carbon which is never added to the 1st element's name in covalent bonding.

• Ava added the pre-fix "mono" to carbon which is never added to the 1^st element's name in ionic bonding.

• Ava added the pre-fix "di" to oxygen which is never added to the 2^nd element's name in covalent bonding.
