When ozone is treated with alkene, aldehyde and ketone are produced, identify which one of the following will produce two moles of butanone.
Correct answer: B. 3,4-Dimethyl-3-hexene.
- A. 2 Butene
- B. 3,4-Dimethyl-3-hexene.
- C. 3-methyl-3-hexene
- D. 2 - Hexene.
Explanation
The ozonolysis of 3,4-dimethyl-3-hexene involves breaking the carbon-carbon double bond, resulting in the formation of carbonyl compounds. The specific carbonyl compounds produced depend on the structure of the initial alkene. In this case, 3,4-dimethyl-3-hexene will produce two similar carbonyl compounds i.e 2 moles of butanone.CH3CH2-C(CH3)=C(CH3)-CH2CH3 + O3 => unstable ozonide => 2 CH3COCH2CH3

About Alkenes
Alkenes are unsaturated hydrocarbons containing a carbon-carbon double bond with sigma and pi components and restricted rotation. Their reactions include electrophilic addition of hydrogen, halogens, hydrogen halides and water, with Markovnikov orientation, oxidation, combustion and polymerisation, while their preparation commonly involves elimination from alkyl halides or alcohols.
