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...

Why is H2 a stable molecule? H2 is stable since all electrons of the molecule can be put into the bonding molecular orbital. O H2 is stable since all electrons of the molecule can be put into the anti-bonding molecular orbital. O H2 is stable since all electrons of the molecule can be put into the 2s bonding state O H2 is stable since all electrons of the molecule hide behind their protons.

Recall that Zaitsev’s rule says that more substituted alkenes are more stable. Therefore, propene is less stable than trans-but-2-ene, which is less stable than 2-methylbut-2- ene, which is less stable than 2,3-dimethylbut-2-ene. In Chapter 7, we showed that we could demonstrate this stability ordering by using heats of hydrogenation. a) Does the same apply for other groups, besides alkyl groups? For example, compare the stability of propene, trans-but-2-ene and trans-1-chloroprop-1-ene to compare the effects of adding a chlorine instead of...

i need help understanding this. From what I know more reactive
is less stable. Isn't it better to have a carbocation next to a EDG
group instead of a EWG. Therefore, if the carbocation ends up next
to a EDG group it will be more stable which is less reactive?
