氯苯

一种芳基氯，其反应性质与普通氯代烷不同。

化学式
C6H5Cl
官能团
卤代芳烃
摩尔质量
112.55 g/mol
Also known as
Monochlorobenzene, Phenyl chloride, Benzene chloride, Chlorobenzol, Chlorbenzene, Monochlorbenzene

概览

Chlorine is bonded directly to an sp2 carbon in the aromatic ring. The usual backside SN2 pathway of a primary chloroalkane is not available at that carbon. A shared C–Cl bond therefore does not justify copying chloroalkane hydrolysis conditions onto chlorobenzene.
