  1. acetaldehyde.
  2. chloral.
  3. phosgene.
  4. trichloro acetaldehyde.

Verified by Toppr

Following reactions are involved in the preparation of chloroform:
CaOCl2+H2OCa(OH)2+Cl2
Then from alcohol,
CH3CH2OH+Cl22HCl−−−CH3CHOacetaldehyde+2HCl

CH3CHO+3Cl2CCl3CHOChlorol or Trichloro acetaldehyde+3HCl (chlorination)

2CCl3CHO+Ca(OH)22CHCl3Chloroform (hydrolysis)
Phosgene (COCl2) doesn't form in the whole process.

Hence, the correct option is C.
