Molecule 2-butene wavelength of light required to cis-trans isomerization
The molecule 2-butene is able to undergo a process called cis-trans isomerization, where the molecule switches from being a cis-alkene to a trans-alkene. This transformation can be induced by light. What is the hybridization of the two Central carbon atoms in 2-butene? The isomerization requires breaking the π bond. Use the table of bond energies to determine the approximate amount of energy (in joules) required to break the C-C π bond in 2-butene, both per mole and per molecule. What...

trans-2-butene?
(Does the carbocation shift from c1 to c2, then a hydride shift
from c2 to c1 (kicking off the water), then another water molecule
takes a hydrogen from c3, with the electrons then going from c3, to
share between c3 and c2?)
Many carbocation rearrangements involve hydride shifts (Section can also migrate to a positively charged carbon. in the direction that leads to a more stable carbocation. 5.12)...
