One of these stereoisomers undergoes elimination by treatment with sodium ethoxide in ethanol much more readily than the other. Which will react faster? Because? Indicate the resulting product.
SOLUTION:
![problem solved problema resuelto](/images/stories/organica-i/alquenos/problemas/problema-01/problema1-02.png)
the molecule [1] it has a single hydrogen ANTI with respect to chlorine and eliminates giving a single alkene. the molecule [2] has two ANTI hydrogens, forming two products in bimolecular elimination.
![problem solved problema resuelto](/images/stories/organica-i/alquenos/problemas/problema-01/problema1-03.png)
the molecule [1] It is eliminated in a high energy conformation -with all the groups in an axial position- and the reaction will be slow because it has a high activation energy.
the molecule [2] it has only the chlorine in axial and will give rise to a transition state of lower energy. faster reaction
