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)

Propane

Answer 2

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