Current Question (ID: 21338)

Question:

$\text{How many } \pi \text{ bonds are present in the product (B) of the reaction illustrated below?}$ $\text{C}_3\text{H}_7 \xrightarrow{\text{KMnO}_4, \text{OH}^-, \Delta} (\text{A}) \xrightarrow{\text{H}_3\text{O}^+} (\text{B})$

Options:

1. $4$
2. $3$
3. $2$
4. $1$

Solution:

$\text{Hint: The aliphatic methyl group is oxidized to the aromatic carboxylic functional group.}$ $\text{Explanation:}$ $\text{Alkyl groups (usually methyl groups) attached directly to an aromatic ring are also oxidized to carboxylic acids.}$ $\text{In presence of } \text{KMnO}_4, \text{potassium benzoate is formed, which on further reaction with } \text{H}_3\text{O}^+ \text{ forms benzoic acid.}$ $\text{The final product is benzoic acid. In benzoic acid 15 sigma and 4 pi bonds are present.}$ $\text{Hence, option 1 is the correct answer.}$
