All of the butanediones have this empirical formula, and there may be other compounds also.
This answer was wrong:
Butadione: first of all: there is only one possible butadion: CH3-C(=O)-C(=O)-CH3 (also named diacetyl)
and secondly butadion is with 6 H atoms (C4H6O2). An alkanon being --C(=O)--, double bonded =O to one 'middle' C atom!.
Right SIX answers or possibilities are (plus 3 enantiomers):
HC(=O)-C'HOH-CH2-CH3 and
HC(=O)-CH2-C'HOH-CH3
CH2OH-C(=O)-CH2-CH3 and
CH3-C(=O)-C'HOH-CH3 and
CH3-C(=O)-CH2-CH2OH
CH3-CH2-CH2-COOH
Improved answer: There are more possibilities:
Esters: Ethyl acetate, methyl propionate, propyl formate and isopropyl formate
Another acid: 2-methylpropanoic acid
Enediols: 3,4-dihydroxy-1-butene (R and S), 1,4-dihydroxy-2-butene (E and Z)
Ether carbonyl compounds: 3-methoxypropanal, 2-methoxypropanal, 2-ethoxyethanal, methoxypropanone
More hydroxy aldehydes: 2-hydroxy-2-methylpropanal, 3-hydroxy-2-methylpropanal
Cyclic compounds: Dioxane, 1,3-dioxacyclohexane, 2-methyl-1,3-dioxacyclopentane, 4-methyl-1,3-dioxacyclopentane (R and S) (and a series of dimethyl-1,3-dioxacyclobutanes if they are viable). There are also cyclic diols such as cyclobutane-1,2-diol (RR, SS and meso) and other cyclobutane isomers, and methylcyclopropanediol isomers. Then there are cyclic and non-cyclic peroxides with O-O bonds.
In short, there are many molecules with the formula: C4H8O2
Because an empirical formula is the simplest form of a compound, we know that the molecular formula contains more atoms than it does. Since we are given the molar mass, we can use this formula. x ( MM of empirical formula ) = MM of molecular formula MM of empirical formula = 12(2) + 1(6) + 16 = 46 MM of molecular formula = 138 46x = 138 x= 138 / 46 x=3 Therefore, the molecular formula is 3(C2H6O) that is C6H18O3
X3Y is the empirical formula
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
NaF is the empirical formula
CH2O because you have to divide by the number they all have in common which is 6

An empirical formula has no data about the structure of a compound.
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
The empirical formula is representative for the chemical composition of a compound; the structural formula is representative for the spatial structure of the compound.
The molecular formula of ethanol is written as either CH3CH2OH or C2H5OH, and its empirical formula is C2H6O. It is often written as EtOH.
NaF is the empirical formula
CH2O because you have to divide by the number they all have in common which is 6
No: The molecular formula is never smaller than the empirical formula.
This is the chemical formula (empirical formula) or the formula unit of this compound.
Empirical formula: C3H2
an empirical formula For an ionic compound, the empirical formula is called a formula unit.
