Phenyl/ Phenyle

Chemical Formula: C6H5

The phenyl group, or phenyl ring, is a cyclic group of atoms formed when a hydrogen atom is removed from the benzene ring. Since the hydrogen atom is not present, there is a vacant point for other atoms or molecules to get attached to the phenyl group.  A phenyl group is also referred to as aryl phenols, They are compounds composed of a phenolic group connected directly to another aromatic ring. (An aryl group is represented by Ar. )

Phenyl groups have six carbon atoms in a hexagonal planar structure, of which five are bonded to hydrogen atoms. They are chemically aromatic and have equal bond lengths between carbon atoms in the ring. It is poorly soluble in water.

The reaction involved in the preparation of Phenyl:

Phenol reacts with bromine and forms a Bromo substituted phenol and hydrogen bromide. 2C6H5OH + 5Br2 → 2C6H2Br2OH + 6HBr

Phenyl making raw materials: Raw materials that are generally used in the manufacture of phenyl are Rosin, pale yellow to deep brown (black type is generally not suitable), Caustic soda, Castor oil, Light creosote oil containing 25 to 30 % carbolic acid.

Types of Phenyl:

  • Green Phenyl: This phenyl is used in removing insects from homes and is nontoxic, biodegradable, and environment friendly. 

  • Black Phenyl: It acts as a powerful disinfectant and is usually in black or dark brown color. (Best Phenyl).

  • White Phenyl: It is usually perfumed with white or milky color. This disinfectant usually helps in removing odors and killing bacteria. ( phenyl for cleaning).

  • phenyl price can range from Rs 40 to Rs 2500 depending on usage.

FAQs (Frequently Asked Questions)

1. What happens when we smell concentrated phenyl or drink it directly?

Direct Contact can irritate and burn the skin and eyes. High exposure to Phenyl Acetonitrile can cause vomiting, weakness, headache, nausea, vomiting.  Breathing Phenyl Acetonitrile can cause irritation in the nose, throat, and lungs causing coughing or shortness of breath.  

Never think of drinking phenyl as you will either die a painful death or your stomach pumped within 15 minutes of drinking the stuff, and maybe come away with nothing worse than severe burns inside the body. 


  1. Store phenyl in a cool, dry, ventilated area away from sources of heat or direct ignition. 

  2. Store it separately from reactive or combustible materials and also out of direct sunlight.

2. Are phenyl and phenol the same?

Phenyl and phenol are often confusing terms. The major difference between phenol and phenyl is that phenol is composed of an oxygen atom whereas phenyl has no oxygen atoms attached to it.

Difference between Phenyl and Phenol:

Phenyl is a benzene ring lacking a Hydrogen atom and is an unstable compound.

It is highly reactive. On the other hand, Phenol is the simplest aromatic alcohol having the formula C6H5OH and is a stable compound. It is less reactive and has a stable structure.

3. Phenyl groups readily undergo oxidation or reduction? Comment.

Phenyl groups tend to resist oxidation and reduction. Phenyl groups have relatively higher stability than aliphatic (non-aromatic) groups.
