Question

In the reaction :
$A\underset{\mathrm{H}{}_2\mathrm{SO}{}_4}{\overset{\mathrm{K}{}_2\mathrm{Cr}{}_2\mathrm{O}{}_7}{\to }}$ acetone $\stackrel{\text{oxidation}}{\to }$ acetic acid, $A$ is

• A. $1$ - propanol
• B. $2$ - butanol
• C. $2$ - propanol
• D. ethanol

Answer 1

Answer: (C)

$\underset{\text{2-propanol}}{\mathrm{CH}{}_3\mathrm{CHOCH}{}_3}$ $\underset{\mathrm{H}{}_2\mathrm{SO}{}_4}{\overset{\mathrm{K}{}_2\mathrm{Cr}{}_2\mathrm{O}{}_7}{\to }}$ $\underset{\text{Acetone}}{\mathrm{CH}{}_3\mathrm{COCH}{}_3}$$\stackrel{\text{oxidation}}{\to }$ $\underset{\text{Acetic acid}}{\mathrm{CH}{}_3\mathrm{COOH}}$
