在高中化学中,炔烃的化学性质和烯烃相似,也有加成、氧化和聚合等反应.这些反应都发生在叁键上,所以叁键是炔烃的官能团.但由于炔烃中的π键和烯烃中的π键在强度上有差异,造成两者在化学性质上有差别,即炔烃的加成反应活泼性不如烯烃,且炔烃叁键碳上的氢显示一定的酸性.炔烃的主要化学反应如下:1.加成反应(1)催化加氢在常用的催化剂如铂、钯的催化下,炔烃和足够量的氢气反应生成烷烃,反应难以停止在
In high school chemistry, acetylene is chemically similar to olefins, with reactions such as addition, oxidation, and polymerization, all occurring on the triple bond, so the triple bond is a functional group of an alkyne, but due to the π bond in the alkyne And the π bond in the olefin in the strength difference, resulting in a chemical difference between the two, that is, alkyne addition reaction is less active than olefins, and alkyne triple bond carbon on the hydrogen showed a certain degree of alkyne The main chemical reactions are as follows: 1. Addition reaction (1) Catalytic hydrogenation Catalysts commonly used in the catalyst such as platinum, palladium, alkyne and hydrogen sufficient amount of hydrogen generated paraffin, the reaction is difficult to stop in
