A mixture of butadiene and ethyne is treated first with osmium tetroxide and then with sodium periodate, with both reagents being in excess (
X
s
).
Your answer will be a three digit number that satisfies the following conditions:
(a) : The first digit will be the number of oxygens in the final product(s).
(b) : The second digit will be the number of carbons in the final product(s).
(c) : The third digit will be the number of hydrogens in the final product(s).
For example, If the final product is C X 6 H X 8 O X 1 , then your answer will be 168.

Nice questions !! KEEP ON posting:)
nice one !
@David Hontz Is the reaction between butadiene and ethyne spontaneous?? Cause, in the solution provided, they are made to react first.

Energetically, 3-pi bonds are broken in the reactants and formation of the 2 sigma-bonds + 1 pi-bond in the product has a negative enthalpy value, therefore the reaction is exothermic and spontaneous. This particular reaction is called D i e l s − A l d e r R e a c t i o n , with an alkyne being used in place of an alkene, and is enthalpically driven. To answer your question; yes, butadiene and ethyne do react spontaneously, which makes these kinds of reactions very fun to work with!
Nice one dude
