An unsaturated hydrocarbon 'A' adds two molecules of `H_(2)` and on reductive ozonolysis gives butane-1, 4-dial, ethanal and propanone. Give the structure of 'A' , write its IUPAC name and explain the reactions involved.

Explanation

The scheme of reaction is
`"Compound"(A) overset("Reductive")underset("Ozonolysis")rarrCH_(3)-underset("ethanal")overset(H)overset(|)(C)=O+O=overset(H)overset(|)C-CH_(2)-underset("Butane 1,4 dial propanonc")(CH_(2)-overset(H)overset(|)C=O+O=overset(CH_(2))overset(|)C-CH_(3)`
Thus , structure of A may be given as
`{:(" "H" " H " "CH_(3)),(" "|" "|" "|),(underset("2-methyl octa-2, 6 diene")(CH_(3)-C=C-CH_(2)-CH_(2)-CH=C-CHrarr)),(8" "7" "6" "5" "4" "3" "2" "1):}`
