苯基类化合物|phenyl
在有机化学中,苯基或苯基环是一个原子的环状群,其式为C?H?。苯基与苯密切相关,可以看作是一个苯环,减去一个氢,氢可以被其他元素或化合物取代,作为官能团。苯基有六个碳原子键合在一个六角形平面环上,其中五个键合在单个氢原子上,其余的碳键合在一个取代基上。苯基在有机化学中很常见。虽然通常用交替的双键和单键来描述,但苯基在化学上是芳香的,并且环中碳原子之间的键长相等。 In organic chemistry, the phenyl group or phenyl ring is a cyclic group of atoms with the formula C?H?. Phenyl groups are closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a functional group. Phenyl groups have six carbon atoms bonded together in a hexagonal planar ring, five of which are bonded to individual hydrogen atoms, with the remaining carbon bonded to a substituent. Phenyl groups are commonplace in organic chemistry. Although often depicted with alternating double and single bonds, phenyl groups are chemically aromatic and have equal bond lengths between carbon atoms in the ring.
