Concept:The sequential oxidation of a primary alcohol involves a two-step pathway before fully converting to a carboxylic acid.
Solution:- A primary alcohol (\( R-CH_2OH \)) contains two oxidizable hydrogen atoms on the carbon bearing the hydroxyl group.
- In the first oxidation step, these hydrogens are removed to form a carbonyl double bond at the terminal position, yielding an Aldehyde (\( R-CHO \)).
- If oxidation continues, the highly reactive aldehyde bond is further oxidized by inserting an oxygen atom, producing a Carboxylic Acid (\( R-COOH \)).
Why other options are incorrect:Ketones are formed by the oxidation of secondary alcohols. Formic acid is a specific final product (if starting from methanol), not the intermediate. Ethers are not oxidation products of alcohols.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
