Current Question (ID: 17625)

Question:

$\text{Which compound is expected to decolorize a cold, basic KMnO}_4 \text{ solution?}$

Options:

1. $\text{CH}_3 - \text{CH}_3$
2. $\text{CH}_3\text{CH}_2\text{CH}$
3. $(\text{CH}_3)_4\text{C}$
4. $\text{CH}_3\text{CH} = \text{CHCH}_2\text{CH}_2\text{CH}_3$

Solution:

$\text{Hint: Baeyer's reagent reacts with an alkene and forms diol as a product.}$ $\text{When an alkene reacts with Baeyer's reagent then diol is obtained as a product.}$ $\text{In this reaction, an alkene reacts with cold basic KMnO}_4 \text{ and forms diol as a product.}$ $\text{The reaction is as follows:}$ $\text{CH}_2=\text{CHCH}_2\text{CH}_2\text{CH}_3 \xrightarrow{\text{KMnO}_4, \text{OH}^- \text{ (cold)}} \text{OHCH}_2\text{CH(OH)CH}_2\text{CH}_2\text{CH}_3$ $\text{Hence, the correct option is the fourth option.}$
