adj.親電子的(吸電子的)

Markovnikov's rule is an important rule of product forecasting in alkene electrophilic addition reaction. 馬氏規(guī)則是在烯烴的親電加成反應(yīng)中預(yù)測產(chǎn)物的重要經(jīng)驗(yàn)規(guī)則,然而它通常的表述有一定的局限性。

Synthesis of the substance from aniline and hexafluoroacetone involves electrophilic addition,acylation and reduction. 其合成一般是以苯胺和六氟丙酮為起始原料,經(jīng)過親電加成、酰化和還原三步反應(yīng)。

Electrophilic aromatic substitution takes place at C5 requiring Activating groups. 在有活化基的情況下可以在C5發(fā)生親電芳香取代反應(yīng)。

It will become deepen to the students' recognization in mechanism of Aryl electrophilic substitution. 這些問題的討論將深化學(xué)生對芳烴親電取代反應(yīng)機(jī)理的認(rèn)識(shí)。

The rate constants of radical and electrophilic addition to alkenes are dominated by different factors. 烯烴的自由基加成和親電加成速率受不同的因素控制。
