In organic chemistry, a vinyl group (abbr. Vi; [1] IUPAC name: ethenyl group [2]) is a functional group with the formula −CH=CH 2. It is the ethylene (IUPAC name: ethene) molecule (H 2 C=CH 2) with one fewer hydrogen atom. The name is also used for any compound containing that group, namely R−CH=CH 2 where R is any other group of atoms.

乙酸乙烯酯 的 化学式 为CH 3 COOCH=CH 2，是一种无色有刺激性液体，也是制备工业中很重要的一种聚合物—— 聚乙酸乙烯酯 的原料。 和其它工业上很重要的化合物一样，乙酸乙烯酯有很多不同的名字或缩写。 乙酸乙烯酯的主要工业制备途径是通过 乙烯 和 乙酸 在 氧 气存在的情况下的 催化反应， 催化剂 为 钯。 [1] 此反应也会产生副反应： 乙酸乙烯酯的制备也可以通过在气态将 乙酸 加入 乙炔 中。 [2] CH 3 COOH （醋酸） + C 2 H 2 → CH 3 COOCH=CH 2 (乙酸乙烯酯) …

2023年1月23日 · What about the first double bond, at 1-2? On the left hand end, there is H and Cl; Cl is higher priority (by atomic number). On the right hand end, there is -CH 2-CH 3 (an ethyl group) and -CH=CH 2 (a vinyl or ethenyl group). Both of these groups have C as the first atom, so we have a tie so far and must look further.

2024年10月12日 · draw the structure of a vinyl (ethenyl) and allyl (2-propenyl) group, and use these names in alkene nomenclature.

与烷烃相比，烯烃和炔烃的后缀分别为 ene 和 yne；对应基团 烯基 和 炔基 则分别为 enyl 和 ynyl，也就是把烯烃炔烃后缀的最后一个字母换成 “yl”。 但同时因为双键、三键的特殊性，烯烃和炔烃又比烷烃多出了许多命名规则和要求。 由于简单烯烃、炔烃的命名与烷烃大致无异，也就是后缀差别，所以这里就直接介绍基团的命名。 烯基和炔基的命名与烷基相同，只需修改对应后缀即可。 如（英文名做出了适当分割），1-甲基乙烯基（异丙烯基）为1 …
