A conjugated alkediene having molecular formula C_13H_22 on ozonolysis

1.	A conjugated alkediene having molecular formula C_13H_22 on ozonolysis yielded ethyl methyl ketone and cyclohexanecarbaldehyde. Identify the diene, write its structural formula and give its IUPAC name.
Answer» Solution :The structures of the products of ozonolysis are : Since, the total number of carbon atoms of the TWO products is 11 (4+7) while the MF of the CONJUGATED diene is `C_13H_22`, therefore , the ozonolysis must have also produced another two carbon product. Further since the GIVEN COMPOUND `(C_13H_22)` is an alkadiene, therefore , this two carbon product. Further since the given compound `(C_13H_22)` is an alkadiene, therefore , this two carbon product must be glyoxal, O=CH-CH=O. Replace the oxygen atoms from these three products by double bonds, the structure of the alkadiene is
