Question

Butan-2-one can be converted to propanoic acid by which of the following?

• A. $NaOH,H^{+}$
• B. Fehling's solution
• C. $NaOH/I_2,H^{+}$
• D. Tollens' reagent

Answer 1

The correct option is C $NaOH/I_2,H^{+}$

Butan-2-one on reaction with $NaOH/I_2$ undergoes iodoform reaction to form iodoform along with the sodium propionate. Sodium propionate is then reacted with $H^{+}$ to form propionic acid as a product.


Tollens' reagent and Fehling's solution convert butan-2-one to sodium propionate only.
