52 Naming Alkenes Alkenes are named as if they were alkanes, but the ”-ane” suffix is changed to ”-ene”. If the alkene contains ...
Naming Alkenes cis/trans notation sometimes breaks down. The first thing to keep in mind is that alkenes are planar and there’s ...
EZ Notation To a certain extent, the Z configuration can be regarded as thecis-isomer and the E as the trans-isomers. This corre ...
