Reductive ozonolysis of Y yields :
Arrange the following in decreasing order of their reactivity towards nucleophilic addition reaction.
CH3COCH3, CH3CH2CHO, HCHO, (CH3)2CHCHO
An alkene gives two moles of HCHO, one mole of CO2 and one mole of on ozonolysis follows by hydrolysis. The structure of this alkene is:
An alkyl halide with molecular formula C6H13Br on dehydro halogenation gave two isomeric alkenes X and Y with molecular formula C6H12. On reductive Ozonolysis, X and Y gave four compounds CH3COCH3,CH3CHO,CH3CH2CHO and (CH3)2 CHCHO. The alkyl halide is
