What is the classification of alcohols based on the number of -OH groups present in the molecule?
Alcohols are classified into monohydric, dihydric, and trihydric based on the number of -OH groups present in the molecule.
What is the classification of alcohols based on the attachment of the -OH group?
What is the classification of alcohols based on the attachment of the -OH group?
Alcohols are classified as primary (1°), secondary (2°), or tertiary (3°) based on the attachment of the -OH group to the carbon atom.
How do alcohols with two or more -OH groups attached to the same carbon atom behave?
How do alcohols with two or more -OH groups attached to the same carbon atom behave?

Study Notes
Classification of Alcohols
- Alcohols can be classified based on the number of -OH groups present in the molecule, which can be:
- Monohydric (one -OH group)
- Dihydric (two -OH groups)
- Trihydric (three -OH groups)
- Polyhydric (more than three -OH groups)
Classification Based on Attachment of -OH Group
- Alcohols can also be classified based on the attachment of the -OH group, which can be:
- Primary (attached to a primary carbon atom)
- Secondary (attached to a secondary carbon atom)
- Tertiary (attached to a tertiary carbon atom)
Alcohols with Multiple -OH Groups
- Alcohols with two or more -OH groups attached to the same carbon atom are unstable and undergo dehydration to form a ketone or an aldehyde.
Isomerism in Alcohols
- Isomerism occurs in alcohols when two or more molecules have the same molecular formula but differ in their structure or arrangement of atoms.
Nomenclature in Alcohols
- Nomenclature is significant in alcohols as it helps to identify and distinguish between different types of alcohols, which is essential in understanding their properties and reactions.
