Question

The number of isomeric alcohols of molecular formula \( \text{C}_4\text{H}_{10}\text{O} \) is:

• A. 2
• B. 4
• C. 7
• D. 8

Hint:

For molecules with the same molecular formula, isomerism occurs due to the different arrangements of atoms and functional groups in space.

Answer 1

The Correct Option is B

Step 1: Determine the molecular formula.
The molecular formula \( \text{C}_4\text{H}_{10}\text{O} \) indicates a compound with four carbon atoms, ten hydrogen atoms, and one oxygen atom. This is the formula for alcohols.
Step 2: Identify possible alcohol isomers.
By rearranging the positions of the hydroxyl group (-OH) on the carbon chain and considering possible branching, the following alcohol isomers can be formed: 1. Butan-1-ol (straight-chain) 2. Butan-2-ol (straight-chain) 3. Isobutanol (branched-chain) 4. tert-Butanol (branched-chain) Thus, there are four isomers.
Final Answer: \[ \boxed{4} \]
