methane
Methane: The simplest saturated hydrocarbon. It is a colorless, flammable gas, slightly soluble in water. It is one of the chief constituents of natural gas and is formed in the decomposition of organic matter. (Grant & Hackh's Chemical Dictionary, 5th ed). methane : A one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms. It is a colourless, odourless, non-toxic but flammable gas (b.p. -161degreeC). | 2.03 | 1 | 0 | alkane;

pyrroles
1H-pyrrole : A tautomer of pyrrole that has the double bonds at positions 2 and 4.. pyrrole : A five-membered monocyclic heteroarene comprising one NH and four CH units which forms the parent compound of the pyrrole group of compounds. Its five-membered ring structure has three tautomers. A 'closed class'.. azole : Any monocyclic heteroarene consisting of a five-membered ring containing nitrogen. Azoles can also contain one or more other non-carbon atoms, such as nitrogen, sulfur or oxygen. | 1.96 | 1 | 0 | pyrrole;
