Configuration of Geometric Isomers (E/Z and Cis/Trans)

TīmeklisWittig Reaction, the Most Important Reaction in Alkene Synthesis. The famous synthetic reaction to create a double bond is the E2 reaction (elimination reaction). However, the conditions for the E2 reaction are extreme, such as reacting under the strong base and high-temperature conditions. There is also the problem of EZ isomerism (cis/trans).

For C 4 H 8, we cannot draw functional isomers. But, for C 4 H 6 molecule, we can draw functional isomers because it is an alkyne. Alkyne group can be represented as two alkene groups. So try to draw isomers of C 4 H 6 molecule. clarinda iowa to walker mn
