When substitution … WebNov 2, 2024 · Elimination means removal. So, a reaction in which only the removal of atoms takes place is called an elimination reaction. Substitution means replacing one thing with another. Such a reaction, in which an atom or group is replaced by other atoms is called a substitution reaction.

Hydrogens on alkene (vinyl hydrogens) usually show up at 4.5 – 7.5 ppm. 2. Trans vs cis. The geometry of the alkene can be determined by looking at the coupling constant of the vinyl hydrogens. Trans alkene has larger coupling constant ...
