benzene ring vs phenyl

Thus, these electrons are said to be delocalized. The Benzene is a planar, six-membered cyclic ring structure with alternating double bonds that are responsible for its aromaticity. A colorless, liquid, volatile hydrocarbon existing in petroleum, A group which is derived from benzene and usually combines with other molecules, The stability is very high when it is alone and not combined with other molecules, “Bn” which is used to represent the benzyl group such as BnOH is marked for benzyl alcohol, “Ph” which is used to represent the phenyl group such as PhH is used to donate the benzene, The bond dissociation energy which is necessary for the detachment of the benzyl C-H bond is 90 kcal/mol, The energy which is needed for the dissociation of phenyl C-H bond is 113 kcal/mol, Widely used in organic synthesis as a safety group for carboxylic acids and alcohols, Widely used in medicines such as Atorvastatin is used to minimize the cholesterol level, and Fexofenadine is used to cure the allergies, The enhanced reactivity characterized the benzylic positions because of the low bond dissociation energy of the benzyl C-H bonds, but benzylic substitutions show increased reactivity in free radical oxidation, halogenation, hydrogenolysis, etc, The lower reactivity characterized the phenylic positions because of high bond dissociation energy, phenyl substances are hydrophobic and resist oxidation. The enhanced reactivity characterized the benzylic positions because of the low bond dissociation energy of the benzyl C-H bonds, but benzylic substitutions show increased reactivity in free radical oxidation, halogenation, hydrogenolysis, etc. Further, they are hydrophobic and non-polar. Its density is 0.964 g/ml and its boiling point is 195 °C. In organic chemistry, the phenyl group or phenyl ring is a cyclic group of atoms with the formula C 6 H 5. The Benzyl Group The benzyl group (abbv. In the case of the benzyl group, it is formed by taking the phenyl group and adding a CH 2 group to where the hydrogen was removed. • Molecular formula of phenyl is C 6 H 5 whereas, in benzyl, it is C 6 H 5 CH 2. -NO2, -COOH). He graduated from the University of California in 2010 with a degree in Computer Science. • Molecular formula of benzene is C 6 H 6 and, for phenyl, it is C 6 H 5. On the contrary, the compounds containing phenyl are used in the medicinal purpose; for example, Atorvastatin is used for lowering the cholesterol level, and Fexofenadine is used for curing the allergies. External Customers, The functional group, which consists of a benzene ring which is directly attached to the CH. Terms of Use and Privacy Policy: Legal. The electron cloud is considered parallel to the plane of the benzene ring, and this particular structure of the benzene ring was first proposed by the Kekule (1872); that’s why benzene structure is also known as Kekule structure. If the substituent attracts electrons from the electron cloud, it is known as electron withdrawing substituent. So the phenyl group is attached with other different molecules through the vacant point, which enhances the reactivity of phenyl.

The abbreviation of benzene is “Bn” which is used to represent the benzyl group such as BnOH is marked for benzyl alcohol; on the flip side, the abbreviation of phenyl is “Ph” which is used to represent the phenyl group such as PhH is used to donate the benzene. The energy which is needed for the dissociation of phenyl C-H bond is 113 kcal/mol. The other sigma bond is formed with a hydrogen atom. These two groups are very different from each other due to the presence of –CH2– group in benzene, which is attached to the benzene ring. The Benzene is a simplest aromatic hydrocarbon made up of only carbon and hydrogen without any other substituents. This is farther downfield than alkene protons, which appear between 4.5-6.5 ppm. • Phenyl is derived from benzene. What is the difference between Phenyl and Benzyl? One each carbon atom is attached with the one hydrogen atom, and in this way, all the six hydrogen atoms are attached with the six carbon atoms. • Molecular formula of benzene is C6H6 and, for phenyl, it is C6H5. phenylamine. Benzene and phenyl seems look the same because they are both aromatic and all aromatic compounds are based on benzene C6H6. The delocalization of the electrons means that there aren’t alternating double and single bonds. All rights reserved. Normally some consider that the benzyl or phenyl group is the same, but it is not. Phenyl is a hydrocarbon molecule with the formula C6H5. Phenethylamine is a primary amine, the amino-group being attached to a benzene ring through a two-carbon, or ethyl group. The phenyl group is based simply on benzene, with one H removed. This overlap of electrons happens in all the six carbon atoms and, therefore, produces a system of pi bonds, which are spread over the whole carbon ring. The phenyl molecular formula is C6H5. It has the molecular formula of C6H6. Fourth, for shorthand and convenience, "phenyl" and "benzyl" are sometimes used to name substituents. Because of the delocalization benzene ring is stable, thus, reluctant to undergo addition reactions, unlike other alkenes. Its structure and some of the properties are as follows. For example, a chlorine attached in this manner would be named phenyl chloride, and a bromine attached in this manner would be named phenyl bromide. Benzene is a stable organic compound, where as a phenyl is an intermediate formed when benzene is subjected to various reaction. Naming of Phenyl Chloride and Phenyl Bromide. Benzene is known as a colorless, liquid, volatile hydrocarbon existing in petroleum; on the other hand, the phenyl is known as a group that is derived from benzene and usually combines with other molecules. 90 kcal/mol is the bond dissociation energy, which is used to break down the benzyl C-H bond; on the contrary, 113 kcal/mol is the bond dissociation energy which is used to dissociate the phenyl C-H bond. The benzyl is widely used in the organic synthesis as a safety group for carboxylic acids and alcohols; on the other hand, the phenyls containing compounds are widely used in the medicines such as Atorvastatin is used to minimize the cholesterol level, and Fexofenadine is used to cure the allergies. Benzene is C6H6 and a pheny group is C6H5* (it can either be phenyl anion (C6H5-), the phenyl cation (c6H5+) or the phenyl radical (C6H5.)) 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. Benzene is considered a ring structure, and its formula is C6H6. What is the difference between Benzene and Phenyl? Group attach to then benzene ring Also they have different solubility in water Benzene is a colorless liquid with a sweet odor. • Phenyl is a substituent whereas benzene is not. Bn), similar to the phenyl group, is formed by manipulating the benzene ring.
