Question

The formula of functional group for aldehyde is :

• A. \( -COOH \)
• B. \( -CHO \)
• C.
• D. \( -OH \)

Answer 1

The Correct Option is B

Step 1: Understanding the Concept: 
Functional groups determine the chemical properties of organic compounds. 
Step 2: Detailed Explanation: 
1. \( -COOH \): Carboxylic Acid group. 
2. \( -CHO \): Aldehyde group (consists of a carbonyl group \( C=O \) bonded to at least one hydrogen). 
3. \( >C=O \): Ketone group (carbonyl group bonded to two carbon atoms). 
4. \( -OH \): Alcohol (Hydroxyl) group. 
Step 3: Final Answer: 
The functional group for an aldehyde is represented as \( -CHO \).
