For example CH4.
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.
The empirical formula for C8H10 is CH5. This is found by dividing the subscripts in the molecular formula by their greatest common factor.
CH4 has the same molecular and empirical formulas.
{CH2- CH-OOC-CH3}N where N is very large and often over 200,000 CH2=CH-OOC-CH3 is the formual for vinyl acetate monomer. The double bond opens up and polymerizes giving the structure above with only a single bond between the CH2 and the CH.
The condensed structural formula for 3-ethyl-2,5-dimethyloctane is CH3CH(CH2CH3)CH(CH3)C(CH3)2CH2CH2CH3.
CH will be the empirical formula and C12H12 will be the molecular formula
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.
CH2 is the empirical formula for C4H8 because it is an alkene and the empirical fomula for ALL alkenes are C(n)H(2n) n being the number of molecules!!! (^-^)
The molecular formula for benzene is C6H6, and the empirical formula is also C6H6. The empirical formula represents the simplest whole-number ratio of atoms in a compound, while the molecular formula gives the actual number of each type of atom in a molecule.
C2H8N2 is molecular formula so empirical formula is C1H4N1
the structural formula for octane(straight chain) is CH3 CH2 CH2 CH2 CH2 CH2 CH2 CH3
Acetylene is C2H2 so its emperical formula is C1H1.
The empirical formula for C8H10 is CH5. This is found by dividing the subscripts in the molecular formula by their greatest common factor.
The molecular formula for styrene is C8H8. This is derived by multiplying the empirical formula (CH) by a factor of 8 to get the molecular formula. Styrene consists of 8 carbon atoms and 8 hydrogen atoms.
The molar mass of styrene (C8H8) is 104 g/mol. The empirical formula is CH, which has a molar mass of 13 g/mol. To find the multiplier to get the molecular formula from the empirical formula, divide the molar mass of the molecular formula by the molar mass of the empirical formula: 104 g/mol / 13 g/mol = 8. This means the multiplier is 8, and the molecular formula of styrene is C8H8.
The empirical formula for C9H20 is C3H7. This is because we divide the subscripts by their greatest common factor, which in this case is 3.
