Identify $\mathrm{X}$ in the following sequence:
  1. $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{OH}$
  2. $\mathrm{CH}_{3} \mathrm{CH}(\mathrm{OH}) \mathrm{CH}_{3}$
  3. $\mathrm{CH}_{3} \mathrm{OCH}_{2} \mathrm{CH}_{3}$
  4. $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CHO}$

Solution

Since the compound $\mathrm{X}\left(\mathrm{C}_{3} \mathrm{H}_{6} \mathrm{O}ight)$ gives iodoform test, it must have $-\mathrm{COCH}_{3}$ groups hence it should be $\mathrm{CH}_{3} \mathrm{COCH}_{3} .$ Therefore $\mathrm{X}$ should $\mathrm{be} \mathrm{CH}_{3} \mathrm{CH}(\mathrm{OH}) \mathrm{CH}_{3} .$ .
