Question

How acetylene is convert into n butyl alcohol?

Answer 1

Acetylene can be converted into n-butyl alcohol in 4 steps:

1) Oxymercuration - Demercuration of Acetylene :

    Acetylene + dil.H2SO4 in the presence of HgSO4 to produce    Acetaldehyde.

2) Aldol Condensation of Acetaldehyde :

Reaction of Acetaldehyde in the presence of Dil. NaOH to form 3-Hydroxybutanal.

3) Heating of product :

  Heating 3-Hydroxybutanal forms 2- Butenal

4) Reduction of 2-butenal:  

   Reduction of 2- butenal in the presence of H2 + Ni/Pd/Pt yields n-butyl alcohol
