Question

The appropriate reagent (s) for the transformation
is / are

  1. Zn + Hg, 523 K    
  2. NH2NH2, OH    
  3. Both (A) and (B)    
  4. NaBH4 or LiAlH4    

The correct answer is: NaBH4 or LiAlH4


    Transformation of C = O group into CH2 in the presence of Zn + Hg is called Clemmensen’s reduction and in the presence of NH2 - NH2/OH- is called Wolf-Kishner Reduction

    The RER in the cell synthesised protein which would be later used in building the plasma membrane. But it is observed that the protein in the membrane is slightly different from the protein made in the RER. The protein was probably modified in another cell organelle.
