Frequently asked questions
What is the molar mass of C12H18O?
The molar mass of C12H18O is 178.28 g/mol, calculated from standard atomic weights for 12 carbon atoms, 18 hydrogen atoms and 1 oxygen atom. The monoisotopic mass is 196.2487 Da.
How many compounds have the formula C12H18O?
CompoundList lists 731 compounds with the molecular formula C12H18O, including 1-(But-2-yn-1-yl)-2-methylcyclohexane-1-carbaldehyde, 2-Isopentyl-5-methylphenol, 1-(Spiro[3.5]nonan-2-ylidene)-2-propanone. 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 C12H18O?
C12H18O 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.
