炔類

Addition Reactions to Alkynes, Hydrogenation, Halogenation and HX. Hydration of alkynes. Tautomerization. 炔烴的加成，氫化，鹵化和HX.

Alkynes have one or more triple bonds, the carbon atoms sharing three pairs of electrons. 鏈炔有一個(gè)或超過三個(gè)共價(jià)鍵，即碳原子享有三對(duì)電子。

Alkanes, alkenes, and alkynes are all hydrocarbons (compounds made up of hydrogen and carbon only). 鏈烷、鏈烯和鏈炔都是碳?xì)浠衔铮儍舻奶己蜌渌M成的化合物）。

Naming of alkynes is very similar to the naming of alkenes, using the root name of the longest carbon chain. 選取同時(shí)含叁鍵和雙鍵最長(zhǎng)的碳鏈做母體，使雙鍵位次盡可能最小。

This article reviews recent methods used in organic synthesis for the stereoselective reduction of alkynes to Z or E alkenes. 綜述了在有機(jī)合成領(lǐng)域中，通過炔烴立體選擇性還原制備Z-或E-烯烴的近期方法。
