Stephens reduction is used to prepare aldehyde from (A) alcohol (B) alkyl cyanides (C) alkanones (D) acid chlorides

Tardigrade Admin · Accepted Answer

Stephens reduction Aldehyde can prepared from alkyl cyanides, e.g. CH3-C≡ N+2[H] xrightarrow[ether]SnCl2/HCl CH3-C underset downarrow H2O/H+H=NH.HCl underset textacetaldehydeCH3CHO +NH4Cl

Aldehyde can prepared from alkyl cyanides, e.g.
$C H_{3} - C \equiv N + 2 [H] S n C l_{2} / H Cl e t h er$
$C H_{3} - C ↓ H_{2} O / H^{+} H = N H . H Cl$
$acetaldehyde C H_{3} C H O + N H_{4} Cl$
