Answer» Correct Answer - B When alkyl or aryl cyanide undergoes reduction in the presence of `SnCl_(2)//dil.` HCl followed by hydrolysis. Aldehyde is formed. This reaction is known as Stepehen reaction. `underset("Alkyl or aryl cyanide")(R-C-=N) overset(SnCl_(2)//H_(2)O) to underset("Aldehyde")underset(H)underset(|)underset(R-Coverset(*)=O+NH_(4)Cl+H_(2)O) underset(darr""^("Hydrolysis"))underset("Imino chloride") underset(H) underset(|)(C)= underset(H) underset(|)N:HCl` |
