Priority of Functional Groups in Organic Compounds according to IUPAC Nomenclature
Explanation:
The IUPAC (International Union of Pure and Applied Chemistry) system of nomenclature is used to name organic compounds. In this system, functional groups are assigned a priority based on their atomic composition and the presence of specific substituents. The correct decreasing order of priority for the given functional groups is as follows:
Option B: COOH, SO3H, CONH2, CHO
1. COOH (Carboxylic Acid)
- Carboxylic acids have the highest priority among the given functional groups.
- The suffix "-oic acid" is added to the parent chain name when a carboxylic acid is present.
- Example: Ethanoic acid (acetic acid)
2. SO3H (Sulfonic Acid)
- Sulfonic acids have the second-highest priority.
- The suffix "-sulfonic acid" is added to the parent chain name when a sulfonic acid is present.
- Example: Methanesulfonic acid
3. CONH2 (Amide)
- Amides have the third-highest priority.
- The suffix "-amide" is added to the parent chain name when an amide is present.
- Example: Ethanamide (acetamide)
4. CHO (Aldehyde)
- Aldehydes have the lowest priority among the given functional groups.
- The suffix "-al" is added to the parent chain name when an aldehyde is present.
- Example: Methanal (formaldehyde)
Therefore, the correct decreasing order of priority for the given functional groups according to the IUPAC system of nomenclature is:
COOH > SO3H > CONH2 > CHO

Therefore, the correct decreasing order of priority for the given functional groups according to the IUPAC system of nomenclature is:
COOH > SO3H > CONH2 > CHO
