In the reaction sequence:Cyclohexane \(\xrightarrow{{hv/C{l_2}}}(X)\xrightarrow{{alc.KOH/\Delta }}(Y)\mathop {\xrightarrow{{(i)\,{O_3}}}}\limits_{(ii)\,{H_2}O/Zn} (Z)\)\((Z)\) will be :
1 Hexanal
2 \(2-\) Hexanone
3 \(3-\) Hexanone
4 Hexanedial
Explanation:
Monochlorination of cyclohexane with chlorine in presence of light gives chloro- cyclohexane.Dehydrohalogenation in presence of alkaline \(KOH\), gives cyclohexene. Ozonolysis by reduction gives hexanedial.
ALDEHYDES, KETONES AND CARBOXYLIC ACID
28221
The given reaction is knows as :
1 Kolbe reaction
2 Tischenko reaction
3 \(MPV\) reaction
4 Oppeneur oxidation
Explanation:
The given reaction is Oppeneur oxidation. In this reaction, a secondary alcohol is oxidized to ketone. Other functional groups present such as amines, sulfides and carbon carbon double bonds are not oxidized. The reagent used is aluminium isopropoxide or aluminum tertiary butoxide in the presence of acetone.
