What is the functional group of phenols?
What is the functional group of phenols?
Phenols are organic compounds which contain a hydroxyl (—OH) group attached to a carbon atom in a benzene ring.
Is a phenol group acidic or basic?
Phenol is a very weak acid and the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring.
What are the physical properties of alcohols and phenols?
Physical state Alcohols : Lower alcohols are colourless liquids at normal temperature. The higher alcohols are colourless, odourless waxy solids. Phenols : Phenols, like alcohols, are either colourless liquids or solids. But they usually turn reddish brown due to atmospheric oxidation.
What are phenols give physical properties of it?
Physical properties of Phenols
- Phenols are colourless liquids or crystalline solids but become coloured due to slow oxidation with air.
- Due to the presence of strong intermolecular hydrogen bonding, phenols have a higher boiling point than the corresponding hydrocarbon or aryl halides.
Is phenol a different functional group?
Although phenols and alcohols show very few similar properties but still their nature is different enough for them to be classified differently. There are 2 different functional group in given example, as marked. Phenol is both a molecule and a functional group (or at least a class of molecules).
Is phenol corrosive to metal?
Reactive with various chemicals and may be corrosive to lead, aluminum and its alloys, certain plastics, and rubber. Freezing point about 105°F.
What are the physical properties of phenols?
Pure phenol is a white crystalline solid, smelling of disinfectant. It has to be handled with great care because it causes immediate white blistering to the skin. The crystals are often rather wet and discolored….Melting and boiling points.
| melting point (°C) | boiling point (°C) | |
|---|---|---|
| C6H5CH3 | -95.0 | 111 |
How do phenols act as antioxidants?
Phenolics are able to act as antioxidants in a number of ways. The interaction of the hydroxyl groups of phenolics with the π-electrons of the benzene ring gives the molecules special properties, most notably the ability to generate free radicals where the radical is stabilized by delocalization.
What is the main chemical characteristic of phenol?
Phenol (also called carbolic acid) 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.
What class of drug is phenol?
Brand names: Blistex. Drug class(es): miscellaneous topical agents. Allantoin/camphor/phenol topical is used in the treatment of: Herpes Simplex.
What are the differences between phenol and alcohol?
Phenol is a type of alcohol with some characteristic features. The key difference between alcohols and phenols is that the alcohols are organic compounds containing -OH group as an essential component whereas the phenols are a group of alcohols which contains -OH group and a benzene ring as essential components.
What are some examples of a phenol?
Protocatechuic acid (PCA)
What does phenyl group mean?
In organic chemistry, the phenyl group or phenyl ring is a cyclic group of atoms with the formula C₆H₅ . Phenyl groups are closely related to benzene. Phenyl groups have six carbon atoms bonded together in a hexagonal planar ring, five of which are bonded to individual hydrogen atoms, with the remaining carbon bonded to a substituent.
