Ingestion of phenyl could have serious health consequences and cause lasting gastrointestinal damage and even death, he said. Ironically animals too were not safe from phenyl either. Drinking water with high concentrations of phenols has caused muscle tremors, difficulty walking and even death in animals.
However, these are different names given to different chemical compounds. The main difference between phenol and phenyl is that phenol is composed of an oxygen atom whereas phenyl has no oxygen atoms.
Aromatic hydrocarbons are nonpolar, and are insoluble in water. However, when other atoms are substituted on the
benzene ring, they may be very water-soluble. For instance, phenol, which has an —OH group attached to the
benzene ring, is very water-soluble.

Phenol is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH). Mildly acidic, it requires careful handling because it can cause chemical burns.
Benzene ring: An aromatic functional group characterized by a ring of six carbon atoms, bonded by alternating single and double bonds. A benzene ring with a single substituent is called a phenyl group (Ph). Benzene. Pyridine. Benzene has a benzene ring, but pyridine does not.

In this method, benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt is mixed with solid sodium hydroxide and reacted at a high temperature. The product of this reaction is sodium phenoxide, which is acidified with aqueous acid to make phenol.
Phenyl group is a type of aryl group. The main difference between aryl and phenyl group is that, the term aryl group is used to name any aromatic functional group whereas the term phenyl is used to name the functional group derived from a benzene ring.
(Long-term exposure means exposure of a year or more.) Benzene causes harmful effects on the bone marrow and can cause a decrease in red blood cells, leading to anemia. It can also cause excessive bleeding and can affect the immune system, increasing the chance for infection.
Benzene is a widely used industrial chemical. Benzene is found in crude oil and is a major part of gasoline. It's used to make plastics, resins, synthetic fibers, rubber lubricants, dyes, detergents, drugs and pesticides. Benzene is produced naturally by volcanoes and forest fires.
BENZENE is a special six carbon ring compound with three alternating double bonds. This structure imparts unique properties to benzene which are different from other ring compounds. The bonds between the carbons in benzene are neither pure single bonds nor pure double bonds, but rather a some hybrid of the two.
Benzene has a sweet, aromatic, gasoline-like odor. Most individuals can begin to smell benzene in air at 1.5 to 4.7 ppm. The odor threshold generally provides adequate warning for acutely hazardous exposure concentrations but is inadequate for more chronic exposures.
The six carbon atoms form a perfectly regular hexagon. All of the carbon-carbon bonds have exactly the same lengths - somewhere between single and double bonds. There are delocalized electrons above and below the plane of the ring, which makes benzene particularly stable.
Benzene is used to make some types of dyes, detergents and pharmaceutical drugs, for example.
Oxygen radicals are produced during benzene metabolism and can induce direct toxic effects. DNA strand breaks and point mutations induced by benzene-initiated toxicity have been linked to the production of ROS in several studies in vitro (137–139).
The usual structural representation for benzene is a six carbon ring (represented by a hexagon) which includes three double bonds. Each of the carbons represented by a corner is also bonded to one other atom. In benzene itself, these atoms are hydrogens.
Phenyl is an emulsion of light creosote oil and water with soap. Creosote oil contains carbolic acid, creosol and other homologues of phenol which exert the necessary germicidal powder adequate incorporation of creosote oil.
White phenyle (sometimes written as phenyl) is a disinfecting agent made from pine oil. It is made by using an emulsifier- a compound that allows an oil to stably make a solution with water. White phenyle is used as a cleaning product to remove odors and kill bacteria.
The phenyl group is based simply on benzene, with one H removed. The benzyl group is based on methylbenzene (toluene), with one H removed from the methyl group.

bluemonkey. sleepy425 said: a phenyl group is electron withdrawing because aromatic rings are electron deficient. a benzyl group is usually electron donating because you have an electron-rich methylene group attached directly to the carbon you're referencing.
Phenols have unique properties and are not classified as alcohols. They have higher acidities due to the aromatic ring's tight coupling with the oxygen and a relatively loose bond between the oxygen and hydrogen.
The phenyl cation is unstable because of the high bond energy for the aromatic C-H bond. And one more reason, the vacant sp2 orbital in phenyl is in the plane of the ring. so it cannot overlap with the orbitals of the π system, so phenyl cation cannot be stabilised by resonance.
If we consider just the phenyl group, it is electron withdrawing by induction(-I effect). This is pretty clear from the pKa values of acetic acid (pKa 4.75) and benzoic acid ( pKa 4.2).
Phenols are organic compounds which contain a hydroxyl (—OH) group attached to a carbon atom in a benzene ring. Their chemical behavior is very distinct from that of alcohols, because they are not capable of undergoing the same oxidation reactions that alcohols participate it.
Phenyl (phenyl group; Ph): A portion of molecular structure equivalent to benzene minus one hydrogen atom: -C6H5. Sometimes abbreviated as Ph. Not to be confused with phenol, fennel, or funnel, or pH. (Phenyl is pronounced with the accent on phen-, whereas phenol is pronounced with the accent on -ol.)
Some of the important functional groups in biological molecules are shown above; they include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl (R-S-H). These groups play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids.
An alcohol is an organic compound with a hydroxyl (OH) functional group on an aliphatic carbon atom. Because OH is the functional group of all alcohols, we often represent alcohols by the general formula ROH, where R is an alkyl group. Alcohols are common in nature.
It is mostly known as phenyl and is from an EWG (electron-withdrawing group).
The amide functional group has an nitrogen atom attached to a carbonyl carbon atom. If the two remaining bonds on the nitrogen atom are attached to hydrogen atoms, the compound is a simple amide. Simple amides are named as derivatives of carboxylic acids.
Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde.
The general format for this kind of naming is: (positions of substituents (if >1)- + # (di, tri, ) + substituent)n + benzene. For example, chlorine (Cl) attached to a phenyl group would be named chlorobenzene (chloro + benzene).
The term benzylic is used to describe the position of the first carbon bonded to a benzene or other aromatic ring. For example, (C6H5)(CH3)2C+ is referred to as a "benzylic" carbocation. The benzyl free radical has the formula C.
