The general formula of monocarboxylic acid:
Correct answer: C. CnH2n+1COOH
- A. CnH2n+2
- B. CnH2nOH
- C. CnH2n+1COOH
- D. CnH2n
Explanation
The general formula of a monocarboxylic acid is indeed CnH2n+1COOH. For a monocarboxylic acid, the general formula represents the presence of a carboxyl group (-COOH) attached to an alkyl group (R). The "R" in the formula represents an alkyl group, which is a hydrocarbon chain, and "n" represents the number of carbon atoms in that alkyl group.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
