An unsaturated hydrocarbon containting 88.8 mass% carbon was allowed to react with excess hydrogen over a Pd catalyst.The amount of hydrogen gas consumed in reaction with 1.00g of the hydrocarbon was 906ml,measured at 298K and 1atm pressure.In a molar mass determination,0.1200g of the hydrocarbon occupied a volume of 67.9ml at 373K and 1.00atm A: What is the molecular formulas of the hydrocarbon? B:Write structures for the isomers that have this molecular formula A的答案我知道是C4H6 答案确实也是C4H6 但B问题我可以画出四个isomer 但是答案却只有三个 是答案错了吗? 答案我认为少了1,2butadiene(1,2丁二烯) 还是有什麽原因不能画出1,2丁二烯 https://imgur.com/gK1pVE --
