Answer»

`CH_(3)OH`
`C_(2)H_(5)OH`
`CH_(3)CHO`
`(CH_(3))_(2)CO`

Solution :`underset("Ethanol")CH_(8)CH_(2)OH+Cl_(2)overset("oxidation")(to)underset("Ethanol")(CH_(3)CHO+2HCl)`
`underset("Ethanol")(CH_(8)CHO)+3Cl_(2) to underset("Chloral")(C Cl_(3)CHO+3HCl)`
`2C Cl_(3)CHO+CA(OH)_(2)to underset("CHLOROFORM")(2CHCl_(2))+underset("Cal. Format")((HCOO)_(2)Ca`
`underset("Acetone")(CH_(3)COCH_(3))+3Cl_(2)to underset("Trichloroacetone")(C Cl_(3)COCH_(3)+3HCl`
`2C Cl_(3)COCH_(3)+Ca(OH)_(2) to 2CHCl_(3)+(CH_(3)COO)_(2)Ca`
