WebPhenyl silicone – or methyl phenyl silicone – is a polydimethylsiloxane with phenyl groups. The phenyl content improves various properties such as oxidation resistance, thermal stability, shear resistance and optical clarity. … 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. Phenyl group is 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 … Zobraziť viac Usually, a "phenyl group" is synonymous with C6H5− and is represented by the symbol Ph or, archaically, Φ. Benzene is sometimes denoted as PhH. Phenyl groups are generally attached to other atoms or groups. … Zobraziť viac Phenyl groups are usually introduced using reagents that behave as sources of the phenyl anion or the phenyl cation. Representative reagents include phenyllithium (C6H5Li) … Zobraziť viac Phenyl compounds are derived from benzene (C6H6), at least conceptually and often in terms of their production. In terms of its electronic properties, the phenyl group is related to a vinyl group. It is generally considered an inductively withdrawing … Zobraziť viac • Media related to Phenyl group at Wikimedia Commons Zobraziť viac
