(1). Why are cis and trans isomers of succinic acid impossible? (2). Define isomerization. (3). What...
Why are there only 3 isomers of pentane? Why doesn't butyne have cis and trans isomers? Why is there no such thing as 3-butyne?
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...
