Question

An organic compound **(X)** with molecular formula $$\mathrm{C}_{3} \mathrm{H}_{6} \mathrm{O}$$ is not readily oxidised. On reduction it gives $$\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}$$ **(Y)** which reacts with **HBr** to give a bromide **(Z)** which is converted to Grignard reagent. This Grignard reagent on reaction with **(X)** followed by hydrolysis give **2,3-dimethylbutan-2-ol**. Compounds **(X)**, **(Y)** and **(Z)** respectively are:

Accepted Answer

B. $$\mathrm{CH}_{3} \mathrm{COCH}_{3}, \mathrm{CH}_{3} \mathrm{CH}(\mathrm{OH}) \mathrm{CH}_{3}, \mathrm{CH}_{3} \mathrm{CH}(\mathrm{Br}) \mathrm{CH}_{3}$$

Answer

A. $$\mathrm{CH}_{3} \mathrm{COCH}_{3}, \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{OH}, \mathrm{CH}_{3} \mathrm{CH}(\mathrm{Br}) \mathrm{CH}_{3}$$

Answer

C. $$\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CHO}, \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{OH}, \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{Br}$$

Answer

D. $$\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CHO}, \mathrm{CH}_{3} \mathrm{CH}=\mathrm{CH}_{2}, \mathrm{CH}_{3} \mathrm{CH}(\mathrm{Br}) \mathrm{CH}_{3}$$
