Oxidation without clevage of sigma bond takes place in alkenes.

Presence of unsaturation in alkenes is detected by using Baeyer's reagent. Alkenes decolourise pink colour of Baeyer's reagent. In presence of Baeyer's reagent, 'syn' addition of -OH groups takes place on both carbons of double bond. The net reaction can be given as,
`R-CH=CH-R overset(KMnO_(4))underset(OH^(-))to R-overset(OH)overset(|)(CH)-overset(OH)overset(|)(CH)-R`
Ozonolysis of alkenes gives ozonide, which on further hydrolysis gives aldehyde and/ or ketone.

Product of ozonolysis gives information about:

Options

A. configuration
B. conformation
C. both of these
D. none of these

Answer

D
