ALDEHYDES, KETONES AND CARBOXYLIC ACID

28220 In the reaction sequence:Cyclohexane $\overset{h v / C l_{2}}{\to} (X) \overset{a l c . K O H / Δ}{\to} (Y) \underset{(i i) H_{2} O / Z n}{\overset{(i) O_{3}}{\to}} (Z)$ $(Z)$ 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 $K O H$ , gives cyclohexene. Ozonolysis by reduction gives hexanedial.
