Frequently asked questions
What is the molar mass of C12H20O?
The molar mass of C12H20O is 180.29 g/mol, calculated from standard atomic weights for 12 carbon atoms, 20 hydrogen atoms and 1 oxygen atom. The monoisotopic mass is 180.1514 Da.
How many compounds have the formula C12H20O?
CompoundList lists 536 compounds with the molecular formula C12H20O, including 4-Methyl-3-(2-methylidenebutyl)cyclohexan-1-one, 3-Cyclopropyl-4-propylcyclohexan-1-one, 3-(But-3-en-1-yl)-4,4-dimethylcyclohexan-1-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 C12H20O?
C12H20O has a degree of unsaturation of 3. 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.
