CCl4 is molecular formula.
A formula unit.
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)
More correct KCl is the formula unit of potassium chloride.
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.
If it is a molecular compound, the smallest unit is called a molecule. If it is an ionic compound, the smallest unit is called a formula unit.
CCI4
A formula unit.
This is the chemical formula (empirical formula) or the formula unit of this compound.
A formula unit.
H2O is a molecular formula. It represents a single molecule of water, which consists of two hydrogen atoms bonded to one oxygen atom. A formula unit typically refers to the simplest whole number ratio of ions in an ionic compound.

For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)
CaCl2 is a formula unit because it represents the simplest ratio of ions in a compound made up of a metal cation (Ca2+) and a nonmetal anion (Cl-). Formula units are used for ionic compounds, while molecular formulas are used for covalent compounds.

A formula unit is a unit that is made up of a metal and a nonmetal. (ex: NaCl) but i think it can also be really big (ex: NaHCO3) A molecule is molecular - only molecular (ex: H2O)
More correct KCl is the formula unit of potassium chloride.
The formula unit of a compound represents the simplest whole number ratio of elements in the compound. This can be determined by looking at the molecular formula of the compound or by performing chemical analysis to find the empirical formula. The formula unit is used in ionic compounds, while the molecular formula is used for covalent compounds.
