A hydrocarbon decolourised bromine water. On ozonolysis it gives 3-methyl butanal and acetaldehyde. Write the structure of the hydrocarbon.

Answer» <html><body><p></p>Solution : Since the given hydrocarbon decolourises bromine <a href="https://interviewquestions.tuteehub.com/tag/water-1449333" style="font-weight:bold;" target="_blank" title="Click to know more about WATER">WATER</a>, it <a href="https://interviewquestions.tuteehub.com/tag/must-2185568" style="font-weight:bold;" target="_blank" title="Click to know more about MUST">MUST</a> be an unsaturated hydrocarbon. On ozonolysis it gives two aldehydes. Therefore, it must be an alkene. The products of ozonolysis are<br/>`<a href="https://interviewquestions.tuteehub.com/tag/underset-3243992" style="font-weight:bold;" target="_blank" title="Click to know more about UNDERSET">UNDERSET</a>("3-methylbutanal")(CH_3 - undersetoverset(|)(CH_3)(C)H - CH_2 - oversetunderset(|)(H)(C)= O)underset("acetaldehyde")(CH_3 - oversetunderset(|)(H)(C) = O)`<br/>The <a href="https://interviewquestions.tuteehub.com/tag/structure-1230280" style="font-weight:bold;" target="_blank" title="Click to know more about STRUCTURE">STRUCTURE</a> of the given alkene can be obtained by joining the oxygenated carbons of the two aldehydes by a double <a href="https://interviewquestions.tuteehub.com/tag/bond-900583" style="font-weight:bold;" target="_blank" title="Click to know more about BOND">BOND</a>.
