Q. An unsaturated hydrocarbon upon ozonolysis gives one mole each of formaldehyde, acetaldehyde and methylglyoxal$(CH_{3}COCHO)$. The structure of the hydrocarbon is
A) $CH_{2} = CH - CH_{2} - CH = CH_{2}$
B) $CH_{2} = CH - C\left( CH_{3} \right) = CH - CH_{3}$
C) $\left( CH_{3} \right)_{2}C = CH - CH_{3}$
D) $CH_{3} - CH = C\left( CH_{3} \right) - CH_{3}$
Explanation
(b)
Knowing the number and arrangement of carbon atoms in aldehydes and ketones the structure of the original alkene can be worked out.
