What is the name for a benzene ring with an OH attached?
phenol
phenol. Phenol has an -OH group attached to a benzene ring and so has a formula C6H5OH.
What is the name of two attached benzene rings?
Naphthalene consists of two benzene rings that are fused together; the resulting molecule is still aromatic, and undergoes the reactions that are typical of benzene itself.
What is benzene with an OH group?
Phenols are organic compounds which contain a hydroxyl (—OH) group attached to a carbon atom in a benzene ring. Phenol, or hydroxybenzene, is the parent compound of the phenols, consisting of an OH group directly connected to a benzene ring.
Why are benzene rings called phenyl?
As this rule suggests that the benzene ring will act as a function group (a substituent) whenever a substituent of more than six (6) carbons is attached to it, the name “benzene” is changed to phenyl and is used the same way as any other substituents, such as methyl, ethyl, or bromo.
Why is benzene called phenyl?
What is benzol example?
1. Also: benzoline. a crude form of benzene, containing toluene, xylene, and other hydrocarbons, obtained from coal tar or coal gas and used as a fuel. 2. an obsolete name for benzene.
What is an OH group called?
A hydroxy or hydroxyl group is a functional group with the chemical formula -OH and composed of one oxygen atom covalently bonded to one hydrogen atom. According to IUPAC definitions, the term hydroxyl refers to the hydroxyl radical (·OH) only, while the functional group −OH is called hydroxy group.
What aromatic compound is attached to oh to become a phenol?
benzene
Phenol, or hydroxybenzene, is the parent compound of the phenols, consisting of an OH group directly connected to a benzene ring.
What is benzene used for?
It ranks in the top 20 chemicals for production volume. Some industries use benzene to make other chemicals that are used to make plastics, resins, and nylon and synthetic fibers. Benzene is also used to make some types of lubricants, rubbers, dyes, detergents, drugs, and pesticides.
What can you do with a metal carport in Ohio?
Our Carport Direct metal structures aren’t just good for sheltering vehicles, either; your carport or shelter can also be a perfect place for hosting your Ohio get-togethers and family gatherings. You can also turn your OH carport into a utility carport by adding enclosed utility space.
How is benzene bonded to the OH group?
Theoretically, when you oxidize benzene (adds an O which pulls an H away from a carbon in the initial ring) you get the ring with the OH bonded at one of the carbons. The O of the OH is bound to the C that originally held the H.
How is a phenyl group attached to a benzene ring?
You get a phenyl group, C6H5, by removing a hydrogen from a benzene ring, C6H6. Like a methyl or an ethyl group, a phenyl group is always attached to something else. Aromatic compounds with only one group attached to the benzene ring Cases where the name is based on benzene chlorobenzene
Which is an example of a halogen attached to benzene?
This is a simple example of a halogen attached to the benzene ring. The name is self-obvious. The simplified formula for this is C 6H 5Cl. You could therefore (although you never do!) call it phenyl chloride. Whenever you draw a benzene ring with one other thing attached to it, you are in fact drawing a phenyl group.
