Isomer Counting
As an example of isomer counting, there are nine structural isomers with molecular formula C3H6O having different bond connectivities. Seven of them are air-stable at ambient temperature, and are given in the table below. An additional two structural isomers are the enol tautomers of the carbonyl isomers, but these are not stable.
Chemical compound | Molecular structure | Melting point (°C) | Boiling point (°C) | Comment |
---|---|---|---|---|
Allyl alcohol | -129 | 97 | ||
Cyclopropanol | 101–102 | |||
Propanal | - 81 | 48 | Tautomeric with (E)-1-propenol and (Z)-1-propenol | |
Acetone | - 94.9 | 56.53 | Tautomeric with 2-propenol | |
Oxetane | - 97 | 48 | ||
Propylene oxide | - 112 | 34 | Can be resolved in two enantiomers | |
Methyl vinyl ether | - 122 | 6 |

Famous quotes containing the word counting:
“If all power is in the people, if there is no higher law than their will, and if by counting their votes, their will may be ascertainedthen the people may entrust all their power to anyone, and the power of the pretender and the usurper is then legitimate. It is not to be challenged since it came originally from the sovereign people.”
—Walter Lippmann (18891974)
