In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ) or Ø.

2024年7月24日 · Oral and nasal phenylephrine are used as nasal decongestants to temporarily unblock a nose or relieve sinus pressure in people with nasal and sinus congestion caused by colds, allergies, or hay fever. While phenylephrine can provide some symptom relief, it doesn't treat the underlying cause or speed recovery.

Phenyl group or phenyl ring or aryl group is an organic functional group with the chemical formula C6H5. Visit BYJU'S to understand the properties, structure and the uses of the phenyl group.

phenyl，英语单词，主要用作名词，作名词时译为“苯基”。

Phenylalanine is the most prominent amino acid. It can be used as a supplement to your diet due to its antidepressant and depressive properties. The appearance of the Phenyl group is a white crystalline solid. The complexity of C 6 H 5 is 27. The odor of the phenyl group is phenyl-like. One unit in the C 6 H 5 structure is covalently bonded.

苯基，指以苯环为官能团的基团，是常见的有机 官能团。 体现 苯 的性质，比如芳香性，能发生亲电反应等。 详见词条“ 苯 ”。 其特征是容易发生 亲电取代，难以发生加成反应，而且光谱上这种大共轭体系一般具有特征吸收峰，对于核磁共振，芳香环对于连接其上的氢一般有很强的去屏蔽效应。 体现 苯 的性质，比如芳香性，能发生亲电反应等。 详见词条“ 苯 ”。 其特征是容易发生 亲电取代，难以发生加成反应，而且光谱上这种大共轭体系一般具有特征吸收峰，对于核磁共振，芳 …

In organic chemistry, a cyclic group of atoms with the formula C6H5 is known as the phenyl group or the phenyl ring. Phenyl groups are closely related to benzene and can also be known as a benzene ring, except minus a hydrogen, which is substitutable by another element or compounds that can serve as a functional group.

A phenyl group is the functional group C 6 H 5. It is the portion of an organic molecule that is derived from a benzene molecule, C 6 H 6, by removal of a hydrogen atom. The term phenyl is used when a benzene ring is connected to a chain of six or more carbonatoms.
