One molecule of an olefinic compound, on ozonolysis, produces one molecule of acetone,one molecule of glyoxal and one molecule of formadehyde. Identify the compound and write its IUPAC name.

Answer»

Solution :The structure of the olefinic hydrocarbon MAY be obtained by arranging the carbonyl compounds obtained on ozonolysis properly (each of the two oxygen atoms of acetone and formaldehyde is PLACED in front of the 2 oxygen atoms of GLYOXAL) followed by eliminating the four oxygen atoms and joining the carbonyl carbons by double BONDS. Thus, the IUPAC name of the starting olefinic compound is 4-methylpenta -1,3-diene.
