which of the following on heating with aqueous KOH produces acetaldehyde?

Options

A. `CH_(3)COCl`
B. `CH_(3)CH_(2)Cl`
C. `CH_(2)ClCH_(2)Cl`
D. `CH_(3)CHCl_(2)`

Answer

D

Explanation

`CH_(3)-overset(O)overset(||)C-Cl overset(KOH(aq))toCH_(3) -overset(O)overset(||)C-OH`
`CH_(3)CH_(2)Cl overset(KOH(aq)) to CH_(3)CH_(2)OH`
`ClCH_(2) -CH_(2) Cl overset(KOH(aq)) to HOCH_(2)-CH_(2)OH`
`CH_(3)CHCl_(2) overset(KOH(aq)) tounderset("Intermediate")(CH_(3)-CH(OH)_(2)) tounderset("Acetaldehyde")(CH_(3)-CH=O)`
