Why phenol is not 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.
Is phenol a primary or secondary alcohol?
The product of alcohol oxidation depends on whether the starting alcohol is a primary, secondary or tertiary alcohol.

What makes a secondary alcohol a secondary alcohol?
A secondary alcohol has the hydroxyl group on a secondary (2°) carbon atom, which is bonded to two other carbon atoms. Similarly, a tertiary alcohol has the hydroxyl group on a tertiary (3°) carbon atom, which is bonded to three other carbons.
How does a phenol differ from an alcohol?
Phenols have a hydroxyl group directly linked to the ring, whereas alcohols, as non-aromatic compounds, have a hydroxyl group linked to the main chain. The difference is one is cyclic, and the other is non-cyclic.
Is phenol secondary alcohol?
Phenol is not an alcohol ! Was this answer helpful?
What is phenol alcohol?
Alcohol. Phenol. The alcohols are a class of organic compounds that hold at least one hydroxyl functional group that is attached to a carbon atom. Phenols, on the other hand, are organic compounds consisting of a hydroxyl group which is attached to an aromatic system of hydrocarbons (arene).
Can phenol react with alcohol?
All the reactions were accompanied by considerable amount of coke formation. Alkylation of phenols by alcohols gave a mixture of 0- and C-alkylated products under the same reaction conditions.
How do phenols differ from alcohols in terms of structure and properties?
Compounds in which an OH group is attached directly to an aromatic ring are designated ArOH and called phenols. Phenols differ from alcohols in that they are slightly acidic in water. They react with aqueous sodium hydroxide (NaOH) to form salts. The parent compound, C 6H 5OH, is itself called phenol.
What’s a secondary alcohol?
Definition of secondary alcohol
: an alcohol that is characterized by the group >CHOH consisting of a carbon atom holding the hydroxyl group and one hydrogen atom and attached by its other two valences to other carbon atoms in a chain or ring and that can be oxidized to a ketone.
How do you determine a secondary alcohol?
Alcohols are organic molecules containing a hydroxyl functional group connected to an alkyl or aryl group (ROH). If the hydroxyl carbon only has a single R group, it is known as primary alcohol. If it has two R groups, it is a secondary alcohol, and if it has three R groups, it is a tertiary alcohol.
How are secondary alcohols made?
To produce a primary alcohol, the Grignard reagent is reacted with formaldehyde. Reacting a Grignard reagent with any other aldehyde will lead to a secondary alcohol. Finally, reacting a Grignard reagent with a ketone will generate a tertiary alcohol.
How do you identify a secondary alcohol?
A secondary alcohol is identified by the color change with the acidified potassium dichromate(VI) solution and the absence of a color change with the Schiff’s reagent might.
What are the chemical differences between alkyl alcohol and phenol?
The key difference between alcohols and phenol is that the hydroxyl group of phenol is bonded directly to a carbon atom of an aromatic ring, whereas in other alcohols, the hydroxyl group is bonded to a saturated carbon atom. This –OH group also determines various properties of these compounds.
Why do phenols sometimes react differently from alcohols despite having the same functional group?
Why do phenols sometimes react differently from alcohols despite the presence of the same functional group? (CH3COOH) is not an alcohol despite having a hydroxyl group. This is because the carbon atom to which the hydroxyl group is attached is unsaturated, as it is double bonded with an oxygen atom.
What is the difference between phenol and alcohol solubility?
Phenols : Phenols also form hydrogen bonds with water and hence are soluble in water. However, the solubility of phenols is much lower than that of alcohols due to the presence of the larger hydrocarbon part (benzene ring).
