BY REDUCTIVE OZONOLYSIS:

An alkene on reductive ozonolysis produce two moles of ethanal. Then the alkene is (A) 2 - butene (B) Ethene (C) Propene (D) 1 - butene

a) Give the structural formulae of the alkene (C_(8)H_(16)) which on reductive ozonolysis gives butan-2-one. b) Write the structure of that compound which on reductive ozonolysis gives propane-1,3-dial. c) Write the products of the reductive ozonlysis of mesitylene with i) (Zn//CH_(3)COOH) ii) NaBH_(4) or LAH. d) Give the structural formulae of the alkene which on reductive ozonolysis gives a mixture of 2-methyl-butanal and pentan-2-one.

An alkene on reductive ozonolysis gives two molecules of CH_(2)(CHO)_(2) . The alkene is:

An olefinic compound on reductive ozonolysis produces formaldehyde, acetaldehyde and 1, 3-propanedial. The IUPAC name of the alkene is

1- Ethylcyclopent -1- ene on reductive ozonolysis followed by aq. NaOH//Delta gives
