When 2-pentanol undergoes oxidation the product is:
Correct answer: C. 2-pentanone
- A. Pentanol
- B. 3-pentanone
- C. 2-pentanone
- D. Pentanoic acid
Explanation
Oxidation of alcohols convert them into aldehydes and ketones. The best reagent for this purpose is acid dichromate. Primary alcohols yield aldehydes whereas secondary alcohols yields ketones. Tertiary alcohols resist oxidation. Hence, 2-pentanol on oxidation forms 2-pentanone.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
