Chloroform cannot be prepared from which of the following?

Options

A. `CH_(3)OH`
B. `C_(2)H_(5)OH`
C. `CH_(3)CHO`
D. `(CH_(3))_(2)CO`

Answer

A

Explanation

`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`
