The common name of benzene -1, 3- diol is
The common name of benzene -1, 3- diol is
Resorcinol
Hydroquinol
Catechol
Cresol
The Correct Option is A
Solution and Explanation
Step 1: Understand the Chemical Structure of Benzene-1,3-diol:
Benzene-1,3-diol, also known as 1,3-benzenediol, is a benzene ring with hydroxyl groups (-OH) attached at the 1st and 3rd positions. The common name of this compound is related to the placement of the hydroxyl groups on the benzene ring.
Step 2: Identify the Common Name:
The common name for benzene-1,3-diol is Resorcinol. This name is widely used in both scientific and industrial contexts for the compound.
Step 3: Analyze the Options:
- Resorcinol is the correct name for benzene-1,3-diol.
- Hydroquinol refers to benzene-1,4-diol, not 1,3-diol.
- Catechol refers to benzene-1,2-diol, which is another isomer of the dihydroxybenzene family.
- Cresol refers to methylphenol, where a methyl group replaces one hydrogen on the benzene ring and does not contain two hydroxyl groups.
Final Answer:
The common name of benzene-1,3-diol is Resorcinol.

Introduction to Organic Chemistry
Organic chemistry is the branch of chemistry that involves the scientific study of organic compounds. Organic chemistry primarily deals with the structure and chemical composition of organic compounds, the physical and chemical properties of organic compounds, and the chemical reactions undergone by these compounds.
Reaction Intermediates in Organic Chemistry:
Intermediates can be understood as the first product of a consecutive reaction. For example, in a chemical reaction, if A→B and B→C, then, B can be said to be the intermediate for reaction A→C. The reactions in organic chemistry occur via the formation of these intermediates.
Reagents in Organic Chemistry:
Reagents are the chemicals that we add to bring about a specific change to an organic molecule. Any general reaction in organic chemistry can be written as:
Substrate + Reagent → Product
Where the substrate is an organic molecule to which we add the reagent. Based on the ability to either donate or abstract electrons, the reagents can be classified as:
- Electrophiles
- Nucleophiles
