Concept Introduction:
Alkenes, upon catalytic hydrogenation, are converted to the corresponding
During hydrogenation, one hydrogen atom gets attached to each of the double bonded carbon atoms.
Catalytic hydrogenation is a stereospecific syn addition; both hydrogens add to the same face of the double bond.
The major product is the one in which the alkene is less hindered and better able to contact the catalyst surface.
In catalytic hydrogenation, the stereo selectivity depends on the direction from which hydrogen atoms are transferred from the catalyst to the double bond.

- Which alkene is this molecule? Choose one of the following : Z, E, ZZ, EE, EZ, ZEarrow_forwardYou are required to synthesize 2-bromopentane from the reaction between an alkene with HBr. Which alkene, 1-pentene or 2-pentene, should you react with HBr in order to get 2-bromopentane? Give an explanation.arrow_forward1,4-Pentadiene (CH2=CH-CH2-CH=CH2) is a liquid at room temperature and has a density of 0.66 g/mL and molar mass of 68.12 g/mol. In a laboratory experiment, 3.80 mL of this compound was treated with 4.80 mL of conc. H2SO4 (100% w/w; molar mass 98.08 g/mol). Note that the density of conc. H2SO4 is 1.84 g/mL. The resulting sulfate ester was then treated with 1.20 mL of water (molar mass 18.02 g/mol) affording, after work- up, 2,4-pentanediol (molar mass 104.15 g/mol) as the crude product. The crude product was then purified by simple distillation, which yielded 2.00 g of pure product. What is the theoretical yield of 2,4-pentanediol expressed in grams? Show calculations. What is the percentage yield of pure 2,4-pentanediol?arrow_forward

Provide a balanced chemical equation to show the reaction between 1,4-pentadiene and sulfuric acid. Do not use molecular formulas in the chemical equation except for sulfuric acid. b. What reactant is the limiting reagent in this chemical equation? Show calculations to support your answer.arrow_forwardThe heat of hydrogenation of cis-2,2,5,5-tetramethyl-3-hexene is -154 kJ (-36.7 kcal)/ mol, while that of the trans isomer is only -113 kJ (-26.9 kcal)/mol. Q.) If a catalyst could be found that allowed equilibration of the cis and trans isomers at room temperature (such catalysts do exist), what would be the ratio of trans to cis isomers?arrow_forwardThe reaction of 3-methylene-1-cyclohexene and HBr yields the four products shown in the attachment. Which two are formed at high temperatures and which two are formed at low temperatures? Why? Why is 1-bromo-3-methylenecyclohexane not formed?arrow_forward
