The hydroxyl group (—OH) is found in the alcohol and phenol functional groups. (Note: that’s not the same as hydroxide, OH-, which is ionic.) – in alcohols, a hydroxyl group is connected to a carbon atom. … (The “parent” molecule of this class is also named phenol: PhOH or C6H5OH.)
Are alcohol and phenol different functional groups?
The alcohols are a class of organic compounds that hold at least one hydroxyl functional group that is attached to a carbon atom.

Can phenol be classified as alcohol?
Alcohols are organic molecules that contain a hydroxyl (-OH) group. Phenols are molecules that contain an –OH group that is directly attached to a benzene ring. Alcohols can be classified as primary, secondary, or tertiary. … This classification is important, because the different classes of alcohols react differently.
Is phenol a different functional group?
They are considered to be different functional groups. Phenols are aromatic compounds where as alcohols are aliphatic compounds. They react differently as they do not have the same properties.
What is the difference between an alcohol and a phenol?
Alcohols are a major type of aliphatic hydrocarbons that contains one or more hydroxyl groups attached to a saturated carbon of the molecule, whereas phenol is an aromatic hydrocarbon that contains a hydroxyl group directly bonded to a phenolic ring (benzene ring).
Which is more acidic alcohol or phenol?
Phenols are stronger acids than alcohols, but they are still quite weak acids. A typical alcohol has a pKa of 16–17. In contrast, phenol is 10 million times more acidic: its pKa is 10. Phenol is more acidic than cyclohexanol and acyclic alcohols because the phenoxide ion is more stable than the alkoxide ion.
What is general formula of alcohol and phenol?
Some of the properties of alcohols depend on the number of carbon atoms attached to the specific carbon atom that is attached to the OH group. … A primary (1°) alcohol is one in which the carbon atom (in red) with the OH group is attached to one other carbon atom (in blue). Its general formula is RCH 2OH.
How do you classify phenol?
Depending on the number of hydroxyl groups attached, phenols can be classified into three types.
- Monohydric phenols: They contain one -OH group.
- Dihydric phenols: They contain two -OH groups. They may be ortho-, meta- or para- derivative.
- Trihydric phenols: They contain three -OH groups.
What are the functional group of alcohol?
Alcohols contain the hydroxy functional group (-OH), bonded to a carbon atom of an alkyl or substituted alkyl 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.
What are examples of phenols?
phenol
- Bisphenol A.
- Chlorophenol.
- Picric acid.
- Salicylic acid.
- Cresol.
- Naphthol.
- Resorcinol.
- Pyrogallol.
What is phenol 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.
Is phenol 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. The more stable the ion is, the more likely it is to form.
Which test shows to show that a phenol is present?
The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols, hydroxamic acids, oximes, and sulfinic acids give positive results as well.
Is phenol primary or secondary alcohol?
Phenol is not an alcohol ! It is a Secondary Alcohol because the Carbon atom on which the -OH group is attached is linked to two other carbon atons ,making it a Secondary Alcohol. Phenol is completely different from an alcohol.
Which kind of hydrogen bonding is involved in monohydric alcohol?
Hydrogen bonds form in alcohols too. For monohydric alcohols in particular, each molecule is capable of forming only two hydrogen bonds. The instantaneous local structure of the grid of hydrogen bonds is therefore created more readily in water, where each molecule can form four hydrogen bonds.
