What functional groups are in phenol?
Phenols are organic compounds which contain a hydroxyl (—OH) group attached to a carbon atom in a benzene ring.
How are alcohols and phenols classified?
On the basis of the number of functional groups, alcohol and phenols are classified as mono-,di-, tri or polyhydric alcohol and phenols. For monohydric alcohols/phenols they contain one -OH group, for dihydric alcohols/phenols they contain two -OH groups,for tertiary alcohols three carbon atoms are directly attached.
Why is phenol not considered as alcohol?
Phenols have unique properties and are not classified as alcohols. They have higher acidities due to the aromatic ring’s tight coupling with the oxygen and a relatively loose bond between the oxygen and hydrogen.
Is alcohol a functional group?
An alcohol is an organic compound with a hydroxyl (OH) functional group on an aliphatic carbon atom. Because OH is the functional group of all alcohols, we often represent alcohols by the general formula ROH, where R is an alkyl group. Alcohols are common in nature.
Is phenol a different functional group?
Phenols and alcohol will be counted as two different types of functional group. Functional group determines the chemical properties of a compound.
What is the difference between a phenol and an alcohol give an example of each compound?
An alcohol can be defined as an organic chemical compound whose molecules contain at least one hydroxyl group….
| Difference Between Alcohol and Phenol | |
|---|---|
| Alcohols show no impact or reaction during tests as they are mostly neutral. | Phenol can change litmus paper red as they are acidic in nature. |
Is phenol considered a secondary alcohol?
If this carbon is bonded to two other carbons, it is a secondary (2o) alcohol. If it is bonded to three other carbons, it is a tertiary (3o) alcohol. When the hydroxyl group is bonded directly to a benzene ring, the compound is classified as a phenol.
What is the name of the functional group that characterizes an alcohol?
hydroxyl group
The functional group of an alcohol is the hydroxyl group, –OH. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond. The electronegativity of oxygen is substantially greater than that of carbon and hydrogen.
