An organic compound \([\mathrm{A}]\left(\mathrm{C}_5 \mathrm{H}_{12} \mathrm{O}\right)\), on reaction with conc. \(\mathrm{H}_2 \mathrm{SO}_4\) at \(443 \mathrm{~K}\) gives \([\mathrm{B}]\) as one of the products. Compound [B] undergoes further reaction with \(\mathrm{O}_3\) and \(\mathrm{Zn} / \mathrm{H}_2 \mathrm{O}\) to give Propanone and Ethanal as products. Identify compound [A]

  1. A Pentan-2-ol
  2. B Pentan-1-ol
  3. C 2- Methylbutan-1-ol
  4. D 3-Methylbutan-2-ol
Verified Solution

Answer & Solution

Correct Answer

(D) 3-Methylbutan-2-ol

Step-by-step Solution

Detailed explanation

The molecular formula of compound [A] is \(C_5H_{12}O\), which corresponds to a saturated alcohol or ether. Since it reacts with conc. \(H_2SO_4\) at \(443 K\) to form an alkene [B], [A] is an alcohol. The reaction of [B] with \(O_3\) followed by \(Zn/H_2O\) (reductive…
