Question

Which of the following compounds will give acetic acid with $\text{KMnO}_{4} / \text{OH}^{-} / \text{Δ}$

• A. $CH_{3}-CHO$
• B. $CH_{3}-CH=CH-CH_{3}$
• C. $CH_{3}-C\equiv C-CH_{3}$
• D. All of these

Answer 1

Answer: (D)

All these compounds can give acetic acid as follows

$1.$

$2.$ $CH_{3}-CH=CH-CH_{3}\overset{\left[\right. O \left]\right.}{ \rightarrow }2CH_{3}-COOH$

$3.$ $CH_{3}-C\equiv C-CH_{3}\overset{\left[\right. O \left]\right.}{ \rightarrow }2CH_{3}COOH$
