The 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 as a functional group. A phenyl group has six carbon atoms bonded together in a hexagonal planar ring, five of which are bonded to individual hydrogen atoms, with the remaining ...
The simplest aryl group is phenyl, which is made up of a benzene ring with one of its hydrogen atom replaced by some substituent, and has the molecular formula C 6 H 5 −. Note that a phenyl group is not the same as a benzyl group , the latter consisting of a phenyl group attached to a methyl group and a molecular formula of C 6 H 5 CH 2 − .
In this type of substitution reaction, one group of the substrate participates initially in the reaction and thereby affects the reaction. A classic example of NGP is the reaction of a sulfur or nitrogen mustard with a nucleophile, the rate of reaction is much higher for the sulfur mustard and a nucleophile than it would be for a primary or secondary alkyl chloride without a heteroatom.
The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. [1] [2] This enables systematic prediction of chemical reactions and behavior of chemical compounds and the design of chemical synthesis.
The aromatic products of the reaction are then separated from the reaction mixture (or reformate) by extraction with any one of a number of solvents, including diethylene glycol or sulfolane, and benzene is then separated from the other aromatics by distillation. The extraction step of aromatics from the reformate is designed to produce ...
In organic chemistry, a substituent is one or a group of atoms that replaces (one or more) atoms, thereby becoming a moiety in the resultant (new) molecule. [1] ( In organic chemistry and biochemistry, the terms substituent and functional group, as well as side chain and pendant group, are used almost interchangeably to describe those branches from the parent structure, [2] though certain ...
Hexaphenylbenzene is an aromatic compound composed of a benzene ring substituted with six phenyl rings. It is a colorless solid. It is a colorless solid. The compound is the parent member of a wider class of hexaarylbenzenes , which are mainly of theoretical interest.
This category includes chemical compounds that include a phenyl group, C 6 H 5 –. (That is, benzene with only one substituent or bond.) For benzene derivatives ( derivatives or structural analogs of benzene ) in which benzene has multiple substituents or bonds, see the parent category, Category:Benzene derivatives .
