                苯基類化合物|phenyl
            
      
            
      
                在有機化學中，苯基或苯基環是一個原子的環狀群，其式為C?H?。苯基與苯密切相關，可以看作是一個苯環，減去一個氫，氫可以被其他元素或化合物取代，作為官能團。苯基有六個碳原子鍵合在一個六角形平面環上，其中五個鍵合在單個氫原子上，其余的碳鍵合在一個取代基上。苯基在有機化學中很常見。雖然通常用交替的雙鍵和單鍵來描述，但苯基在化學上是芳香的，并且環中碳原子之間的鍵長相等。
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.
