No. Methyl (CH₃) is a group with three hydrogen atoms bonded to carbon. Methylene (CH₂) has only two hydrogen atoms bonded to carbon.
No, it is a highly technical term specific to chemistry and related sciences. It has no application in general conversation.
Methylene blue is a specific chemical compound (an organic dye and medication) that contains the methylene group in its structure. It is used in biology labs and some medical treatments.
In British English: /ˈmɛθɪliːn/ (METH-i-leen). In American English: /ˈmɛθəˌlin/ (METH-uh-leen). The primary stress is on the first syllable.
