On oxidation, an alcohol gives an aldehyde having same number of carbon atoms as in alcohol, the alcohol is____
Correct answer: A. Primary Alcohol
- A. Primary Alcohol
- B. Secondary Alcohol
- C. Tertiary alcohol
- D. None of These
Explanation
Oxidation of a primary alcohol first gives an aldehyde containing the same number of carbon atoms, for example CH3CH2OH gives CH3CHO. Secondary alcohols give ketones, while tertiary alcohols resist oxidation under ordinary conditions. Students may choose secondary alcohol because both primary and secondary alcohols can be oxidized, but only the primary product is an aldehyde.

About Alcohols
Alcohols contain a hydroxyl group attached to a saturated carbon atom and are classified as primary, secondary or tertiary. Their nomenclature, hydrogen bonding, acidity, oxidation, dehydration, reaction with sodium and conversion to haloalkanes are covered, along with the distinction between alcohols and phenols, where the hydroxyl group is attached directly to an aromatic ring.
