Methylene (IUPAC name: methylidene, also called carbene or methene) is an organic compound with the chemical formula CH 2 (also written [CH 2] and not to be confused with compressed hydrogen, which is also denoted CH 2). It is a colourless gas that fluoresces in the mid-infrared range, and only persists in dilution, or as an adduct.

The chemical formula of methylene is CH2. Methylene is fluid-like chloroform in appearance and odour, but differing in its boiling point and its specific gravity. Methylene was used as the name for methanol, which is wood alcohol, CH3OH, in the early 19th century.

亚甲基（-CH2-）常在化学中表示 仲碳原子 （secondary carbon） 常来表示有两个键被取代的 碳原子。 它与其它 原子团 相连，单独可叫亚甲基，也做-CH2- (methylene)。 亚甲基上的两个 氢原子 分别位于 碳原子 的两侧。 :CH2电中性分子，称为“ 卡宾 ”或“ 甲烯 ”，是高度活泼的 反应中间体。 亚甲基常是 碳链 的 组成单元，会增加化合物的 亲脂性。 亚甲基（-CH2-）常在化学中表示仲碳原子（secondary carbon） 常来表示有两个键被取代的碳原子。 它与其它原子团相连，单独 …

This stands in contrast to a situation where the carbon atom is bound to the rest of the molecule by a double bond, which is preferably called a methylidene group, represented =CH2. [2] . Formerly the methylene name was used for both isomers.

An older name for methylidene group (=CH 2), a part of a molecule connected to another atom by a double bond. Methylene (compound) (CH 2), an organic compound.

The name indicates two methyl (CH 3) groups, one on the second carbon atom and one on the third. Finally, fill in all the hydrogen atoms, keeping in mind that each carbon atom must have four bonds. The parent chain is heptane in this case, indicating seven carbon atoms in the LCC.

Methylene (systematically named methylidene and dihydridocarbon, and is also called carbene) is an organic compound with the chemical formula CH2 (also written [CH. 2. It is a diatomic radical and has a matter structure forming ethers analogous to those of gas.
