No, neither methanon nor ethanon exist. The simplest alkanon is propanon CH3-C(=O)-CH3.
H2C(=O) is methanal and H3C-CH(=O) is ethanal
when a ketone functional group is added to methane, it becomes methanone. ketone is added only in the middle of the carbon chain, but methanone is onle 1 C chain. Therefore, methanone does not exist
There is no such molecule known (in English) as "methanone". Methanone could be an incorrect reference to any of these three molecules: formaldehyde, acetaldehyde, or acetone.
All of the herbal incense brands contain JWH compounds. Mostly they have been analyzed and shown to contain one or more of the following compounds: JWH-073 naphthalen-1-yl-(1-butylindol-3-yl)methanone JWH-081 4-methoxynaphthalen- 1-yl- (1-pentylindol- 3-yl)methanone JWH-200 (1-(2-morpholin-4-ylethyl)indol-3-yl)-naphthalen-1-ylmethanone JWH-250 2-(2-methoxyphenyl)-1-(1-pentylindol-3-yl)ethanone
The hydrocarbon methane consists of a carbon atom bonded to four hydrogen atoms arranged in a tetrahedral shape. That its, the bonds to the hydrogen atoms point to the corners of a triangular pyramid. Use the link below to see an image that should help lock it in.
