Question

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

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

Answer 1

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

Propanoic acid is formed from butan-$2$-one when iodoform reaction takes place. In this reaction the acid formed has one $C$ lesser in number than the substrate molecule.
