Ozonolysis of an alkene produces only one dicarbonyl compound. The structure of the alkene is
H3C - CH = CH - CH3
CH3 - CH = CH - CH = CH3
From the following compounds, choose the one which is not aromatic.
B.
For a compound to be aromatic,
(i) It should be planar
(ii) It should have ( 4n + 2) electrons
(iii) It should be able to delocalise its electron density.
Among the given compounds, 1, 3, 5, 7-cyclooctatetraene or cyclooctatetraene is not aromatic as its structure is non-planar.
The major products obtained during ozonolysis of 2, 3-dimethyl-1-butene and subsequent reductions with Zn and H2O are
methanoic acid and 2-methyl-2-butanone
methanal and 3-methyl-2-butanone
methanol and 2, 2 -dimethyl-3-butanone
methanoic acid and 2-methyl-3-butanone
1,4-dimethylbenzene on heating with anhydrous AlCl3 and HCl produces
1, 2-dimethylbenzene
1, 3-dimethylbenzene
