No, you do not. The prefix -mono in front of the first element of a binary covalent compound is dropped.
For example, if we take the molecular compound CO, we do not call it "Monocarbon Monoxide". It is called "Carbon Monoxide".
The name for XeF6 is xenon hexafluoride. The Greek prefix hexa- means six. Since Xe has no subscript, it is understood to be one, and the prefix mono- is not used for the first element in a binary covalent compound.
No prefix is used if it is an ionic compound. If it is a binary molecular compound, the prefix mono- is not used in front of the name of the first element. For example, the ionic compound Na2O is sodium oxide, not disodium monoxide, and the molecular compound CO2 is carbon dioxide, not monocarbon dioxide.
The Greek prefix for 3 is "tri-". So, in the covalent compound C3H8, the cation represented by the Greek prefix is tri- (as in tricarbon).
The Greek prefix used to represent the anion in the covalent compound CO2 is "di-" because there are two oxygen atoms in the compound.
The names of binary acids do not begin with bi. The names of binary acids being with the "hydro" prefix, then the root of the nonmetal element, then they end with "ic".
The name for XeF6 is xenon hexafluoride. The Greek prefix hexa- means six. Since Xe has no subscript, it is understood to be one, and the prefix mono- is not used for the first element in a binary covalent compound.
The molecular formula for iodine pentafluoride is IF5. No prefix in front of iodine is understood to be one, but mono- is not used for the first element in a binary covalent compount. The prefix penta- means five, so the subscript for fluoride is 5. Unfortunately, there is no way to write the 5 as a subscript.
No prefix is used if it is an ionic compound. If it is a binary molecular compound, the prefix mono- is not used in front of the name of the first element. For example, the ionic compound Na2O is sodium oxide, not disodium monoxide, and the molecular compound CO2 is carbon dioxide, not monocarbon dioxide.
The Greek prefix for 3 is "tri-". So, in the covalent compound C3H8, the cation represented by the Greek prefix is tri- (as in tricarbon).
The Greek prefix used to represent the anion in the covalent compound CO2 is "di-" because there are two oxygen atoms in the compound.
The Greek prefix used to represent the cation in the covalent compound C2H6 is "di-". This indicates that there are two carbon atoms present in the compound.
The names of binary acids do not begin with bi. The names of binary acids being with the "hydro" prefix, then the root of the nonmetal element, then they end with "ic".
The Greek prefix used to represent the anion in the covalent compound CO3 is "tri-" which signifies three oxygen atoms in the anion. This compound is called carbonate.
The Greek prefix used to represent the anion in the covalent compound CO2 is "di-" because there are two oxygen atoms in the molecule.
For the anion in the covalent compound CH3, the Greek prefix used to represent it is "meth-." So, the anion in CH3 would be called "methide."
One component of a binary ionic compound is a metal element.
The Greek prefix used to represent the cation in the covalent compound C3H8 is "tri-." This indicates that there are three carbon atoms present in the cation.
