Further since the <a href="https://interviewquestions.tuteehub.com/tag/given-473447" style="font-weight:bold;" target="_blank" title="Click to know more about GIVEN">GIVEN</a> <a href="https://interviewquestions.tuteehub.com/tag/compound-926863" style="font-weight:bold;" target="_blank" title="Click to know more about COMPOUND">COMPOUND</a> `(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 <br/> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/PR_CHE_02_XI_C13_E02_002_S02.png" width="80%"/></body></html>
