What is the formula unit of molecular compounds?

The molecular formula is the formula of a discrete (single) molecule of the substance.The formula unit is generally defined in the same way as the empirical formula, which is the simplest whole number ratio of the elementsChemical formula includes both molecular and formula units.Examples:-Benzene a molecule consisting of a ring of 6 carbon atoms each with a hydrogen attached:-molecular formula C6H6formula unit CH (which is the result you would get if you analysed the compound and worked out the atomic ratio of carbon to hydrogen.NaCl is ionic so you cannot write a molecular formula you express the compound simply as the formula unit (empirical formula)- in its simplest case NaCl (never Na2Cl2 or some such)How can you tell whether a formula is molecular formula or a formula unit. Well if the formula could be "simplified" like benzene C6H6 could be simplified to CH then you know its a molecular formula. Something like SO2 and TiO2, well you need to be told. (SO2 is molecular, TiO2 is ionic)


Would ionic or covalent molecules use the molecular formula or empirical formula?

What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.


Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?

Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.


How are the empirical and molecule formulas for a compound related?

The empirical formula of a compound represents the simplest whole-number ratio of the elements present, while the molecular formula indicates the actual number of atoms of each element in a molecule of the compound. The molecular formula can be a multiple of the empirical formula, meaning that it may contain the same elements in a proportion that is a whole number multiple of the empirical ratio. For example, if the empirical formula is CH₂, the molecular formula could be C₂H₄, C₃H₆, etc., depending on the actual number of atoms in the molecule.


Which compound is an isomer of C2H5OC2H5?

An isomer of C2H5OC2H5 (diethyl ether) is C4H10O, specifically butanol (which has multiple structural isomers such as n-butanol, isobutanol, and others). These compounds share the same molecular formula but differ in their structural arrangement. Another possible isomer could be 1,2-dimethoxyethane, which retains the same molecular formula while presenting a different structure.

How do you calculate Molecular formula from empirical formulaWhat could you do with that information to determine that the empirical and molecular formulas are related to one another by a factor of 6?

In order to find molecular formula from empirical formula, one needs to know the molar mass of the molecular formula. Then you simply divide the molar mass of the molecular formula by the molar mass of the empirical formula to find out how many empirical formulae are in the molecular formula. Then you multiply the subscripts in the empirical formula by that number.

What could be a molecular formula for the empirical formula C2H2?

The molecular formula for the empirical formula C2H2 is also C2H2. The empirical formula gives the simplest whole number ratio of atoms present in a compound, whereas the molecular formula provides the actual number of atoms of each element in a molecule.


What is the molecular formula of a compound with an empirical formula of CH?

The molecular formula of a compound with an empirical formula of CH is likely to be CH, as there is only one carbon atom and one hydrogen atom in the empirical formula. In this case, the empirical formula is also the molecular formula.

What is the common name for CHI?

Chicago.CHI is not valid as a molecular formula; such a compound could not possibly be stable.


How are molecular and empirical formulas related?

An empirical formula may or may not be the same as a molecular formula. The empirical formula of a compound shows the smallest whole-number ratio of the atoms compound. The molecular formula tells the actual number of each kind of atom present in a molecule of the compound.
