Iso-Butyl alcohol has following carbon attached to hydroxyl group:
Correct answer: D. Primary
- A. Tertiary
- B. Secondary
- C. Quaternary
- D. Primary
Explanation
Primary carbon is that carbon atom that is bonded to only one carbon atom. Secondary carbon is bonded to two carbon atoms. Tertiary carbon is bonded to three carbon atoms while Quaternary carbon is bound to four carbon atoms. Isobutyl alcohol, 2-Methyl-1-propanol, or isobutanol, is a three-carbon chain, with the OH group at the primary, end carbon, and a methyl group on the middle carbon.

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.
