The correct Answer is A-2, B-3, C-4, D-1
Explanation
Organic compounds are systematically named according to IUPAC nomenclature rules, which often involve using specific suffixes to denote the presence of particular functional groups. These functional groups determine the chemical properties of the compounds.
Statement-wise Analysis
- A. Ketone - 2. -one: Correct
Ketones are organic compounds containing a carbonyl group (C=O) bonded to two alkyl or aryl groups. The characteristic suffix used in IUPAC nomenclature for ketones is "-one". For example, propanone (acetone).
- B. Carboxylic acid - 3. -oic acid: Correct
Carboxylic acids are organic compounds characterized by a carboxyl group (-COOH). The IUPAC suffix for carboxylic acids is "-oic acid". For example, ethanoic acid (acetic acid).
- C. Alcohol - 4. -ol: Correct
Alcohols are organic compounds containing a hydroxyl group (-OH) attached to a saturated carbon atom. The IUPAC suffix for alcohols is "-ol". For example, ethanol.
- D. Aldehyde - 1. -al: Correct
Aldehydes are organic compounds containing a formyl group (-CHO). The IUPAC suffix for aldehydes is "-al". For example, ethanal (acetaldehyde).
Key Takeaway
The IUPAC nomenclature for organic compounds assigns specific suffixes to functional groups, such as "-one" for ketones, "-oic acid" for carboxylic acids, "-ol" for alcohols, and "-al" for aldehydes.
