The major product D formed in the following reaction sequence is : [figure]

  1. [figure]
  2. [figure]
  3. CH3CH2OH
  4. CH3CH2Cl

Answer

(3) CH3CH2OH

Solution

CH3OH SOCl2 CH3Cl (A)

CH3Cl [aq. EtOH]KCN CH3CN (B)

CH3CN [EtOH]Na(Hg) CH3CH2NH2 (C) (Mendius reduction)

CH3CH2NH2 NaNO2 + HCl [CH3CH2N2 Cl ]

[CH3CH2N2 Cl ] H2O CH3CH2OH + N2 + HCl

D (major) = ethanol, CH3CH2OH.
