WebMay 12, 2014 · It will most likely attack at the the $\pi$ type orbitals since bromine is an electrophile. The mechanism is analogous to the addition of bromine to ethene, which is nicely described at chemguide.co.uk. The essential part is the attack of the bromine at the HOMO(s). The ring opening reaction can be reversed by adding sodium. WebJan 23, 2024 · Ethene is the formal IUPAC name for H 2 C=CH 2, but it also goes by a common name: Ethylene. The name Ethylene is used because it is like an ethyl group ( C H 2 C H 3) but there is a double bond between the two carbon atoms in it. Ethene has the formula C 2 H 4 and is the simplest alkene because it has the fewest carbons (two) …
