A conjugated alkadiene having molecular formula `C_(13)H_(22)`, on ozonolysis, yielded ethyl methyl ketone and cyclohexanecarbaldehyde. The IUPAC name of the diene is

A

1-cyclohexyl-2-methylhexa-1,3-diene

B

1-cyclohexyl-4-methylhexa-1,3-diene

C

1-cyclohexyl-1-methylhexa-1,4-diene

D

1-cyclohexyl-3-methylhexa-1,4-diene

Text Solution

Verified by Experts

The correct Answer is:
B
The structures of the products of ozonolysis are

Since the number of carbon atoms of the two products is 11(4+7), therefore, the ozonolysis must have also produced another two carbon atom product. Further, since the given compound `(C_(13) H_(22))` cis an alkadiene, this two carbon compound must be glyoxal. OHCCHO. Replace the oxygen atoms from these three products by double bonds, the structure of alkadiene is
