Question

What is obtained, when propionic acid is reduced with HI, in presence of phosphorus?

• A. Ethane
• B. Propane
• C. Butane
• D. None of these

Answer 1

Answer: (B)

On heating with HI and phosphorus, acids get reduced to give corresponding alkanes. $C{H}_{3}C{H}_{2}COOH\underset{\text{reduction}}{\overset{\text{HI,P}}{\to }}\underset{\text{Propane}}{C{H}_{3}C{H}_{2}C{H}_3}$
