Frequently asked questions
What is the molar mass of C12H21NO?
The molar mass of C12H21NO is 195.31 g/mol, calculated from standard atomic weights for 12 carbon atoms, 21 hydrogen atoms, 1 nitrogen atom and 1 oxygen atom. The monoisotopic mass is 199.1874 Da.
How many compounds have the formula C12H21NO?
CompoundList lists 463 compounds with the molecular formula C12H21NO, including 3-((1-Methylcyclohexyl)methyl)pyrrolidin-2-one, 1-{3-Azabicyclo[3.2.1]octan-3-yl}-2,2-dimethylpropan-1-one, 1-(2,2-Dimethylhex-5-en-1-yl)pyrrolidin-3-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 C12H21NO?
C12H21NO 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.
