Frequently asked questions
What is the molar mass of C12H18O2?
The molar mass of C12H18O2 is 194.27 g/mol, calculated from standard atomic weights for 12 carbon atoms, 18 hydrogen atoms and 2 oxygen atoms. The monoisotopic mass is 201.1746 Da.
How many compounds have the formula C12H18O2?
CompoundList lists 934 compounds with the molecular formula C12H18O2, including 1,3-Diethoxy-2-ethylbenzene, 3',5'-Dimethyl-2-oxaspiro[bicyclo[3.1.0]hexane-3,1'-cyclohexan]-4-one, 4',5'-Dimethyl-2-oxaspiro[bicyclo[3.1.0]hexane-3,1'-cyclohexan]-4-one. Compounds that share a formula are isomers. They contain the same atoms arranged differently, so their properties, uses and prices can be very different.
What is the degree of unsaturation of C12H18O2?
C12H18O2 has a degree of unsaturation of 4. That is the total number of rings and pi bonds (a double bond counts as one, a triple bond as two) in any structure with this formula.
