What is the total number of valid constitutional isomeric structures that represent alcohols for the — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

The molecular formula $C_4H_{10}O$ represents saturated, acyclic compounds. The alcohol isomers are: 1) butan-1-ol, 2) butan-2-ol, 3) 2-methylpropan-1-ol (isobutyl alcohol), and 4) 2-methylpropan-2-ol (tert-butyl alcohol). Ether isomers are excluded by the question parameter.
