Methine vs. Methane — What's the Difference?

A trivalent group or radical consisting of a carbon and a hydrogen atom, specifically the group =CH—; also called methene or methenyl. Also (especially in Dye Chem.): designating a dye, pigment, etc., containing one or more such groups.

Methane (US: , UK: ) is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen). It is a group-14 hydride and the simplest alkane and is the main constituent of natural gas.

(organic chemistry) The tervalent functional group, -CH=, having one single bond and one double bond

An odorless, colorless, flammable gas, CH4, the major constituent of natural gas, that is used as a fuel and is an important source of hydrogen and a wide variety of organic compounds.

The simplest aliphatic hydrocarbon, CH₄, being a constituent of natural gas, and one of the most abundant greenhouse gases.

Any of very many derivatives of methane.
