What is another word for methylene group?
Pronunciation: [mˈɛθɪlˌiːn ɡɹˈuːp] (IPA) 
The methylene group is a common structure found in organic chemistry, consisting of a carbon atom bonded to two hydrogen atoms. Synonyms for the methylene group include methine group, CH2 group, and methylidene group. Methine group is a more specialized term, referring specifically to a carbon atom bonded to three other atoms, but it is often used interchangeably with methylene group. The CH2 group is a more general term that does not specify the nature of the bonds to the carbons adjacent to the methylene group. Methylidene group is less commonly used than the other synonyms, but it is still a valid term with the same meaning as methylene or methine group.
