Identify A and B in the following reaction CH ₃- CH ₃ B CH ₃ COOH A CH ₃ CH ₂ OH A B
Options
- AHI + red P LiAlH ₄
- BNi / LiAlH ₄
- CLiAlH ₄ HI + red P
- DPd _ - BaSO ₄ Zn + HCl
Correct answer
C. LiAlH ₄ HI + red P
Step-by-step solution
Acetic acid on reduction with lithium aluminiumhydride ( LiAlH ₄ ) gives ethyl alcohol while on reduction with HI and red P gives ethane. CH ₃ COOH LiAlH ₄ CH ₃ CH ₂ OH ethyl alcohol CH ₃ COOH Red P + HI CH ₃- CH ₃ Hence, reagent A and B are respectively LiAlH ₄ and HI / red P.
