Question

Jones reagent is used in which of the following conversions?

• A. CH$_3$CH$_2$CH$_2$OH $\rightarrow$ CH$_3$CH$_2$COOH
• B. CH$_3$CH$_2$CH$_2$OH $\rightarrow$ CH$_3$CH$_2$CHO
• C. C$_6$H$_5$CH$_2$OH $\rightarrow$ C$_6$H$_5$CH$_2$OH
• D. CH$_2$=CHCH$_3$ $\rightarrow$ 2H$_3$CCHO

Hint:

Jones reagent oxidizes primary alcohols to acids and secondary alcohols to ketones.

Answer 1

The Correct Option is A

Jones reagent (CrO$_3$ in dilute H$_2$SO$_4$) is a strong oxidizing agent used to oxidize primary alcohols to carboxylic acids.
In the given options, only (1) shows a primary alcohol being converted into a carboxylic acid.
