Answer:
(E)-2-pentene has the smaller heat of hydrogenation. There is less steric strain between the alkyl substituents in the (E)-isomer than in the (Z)-isomer.
Please do give a thumbs up.
which has the smaller heat of hydrogenation, (E)-2-pentene or (Z)-2-pentene?
i
know with E pentene it would be trans and Z pentene it would be
cis. but im confused at to what that has to do with heat of
hydrogenation
16. Which has the smaller heat of hydrogenation, (E)-2-pentene or (Z)-2-pentene? What is the structural origin of this difference? Please give your answer here:
Draw the product of the hydrogenation of cis-2-pentene. Draw all hydrogen atoms.
Draw the product of the hydrogenation of cis-2-pentene. Draw all hydrogen atoms. Pd + H2 → CH2-CH3
Both the E and Z diastereomers of 2-pentene can react with bromine to from 2,3-dibromopentane. (E) Br2 arty 4 stereoisomers a. Draw the 4 possible stereoisomers of 2,3-dibromopentane. b. Using a mechanism, prove that E-2-pentene can only form the 2S, 3R and 2R, 3S stereoisomers. c. Using a mechanism, prove that Z-2-pentene can only form the 2S,3S and 2R, 3R stereoisomers.
b. Assume that you carried out separate reactions of bromine with (E)-2-pentene and (Z)-2- pentene. After isolating, purifying and determining the melting point of the product from each reaction, you found that the melting points were significantly different. Explain why.
Modify the given structure to show the product of the hydrogenation of cis-2-pentene. Include all hydrogen atoms. You may need to change bonds, add atoms, or remove atoms.
Does 2-methyl-2-pentene have any Geometric isomers? If so, are they E or Z?
