Question

Which set of reaction condition is best suited for the preparation of $5-oxohexanoic$ acid from $5-bromo-2-pentanone$?

• A. i) $NaCN$ in ethanol; ii) $H_3{O}^{(+)}$ & heat
• B. i) $NaC\equiv CH$ in ether; ii) aqueous $KMn{O}_4$ & heat
• C. i) Mg in ether; ii) $C{O}_2$, then $H_3{O}^{(+)}$
• D. i) $NaOH$ in ethanol; ii) John's regent

Answer 1

The correct option is A i) $NaCN$ in ethanol; ii) $H_3{O}^{(+)}$ & heat

Here Sodium Cyanide in ethanol and Hydronium ion with heat are used for the preparation of 5-oxohexanoic acid and 5-bromo-2-pentanone
