The question is what is the movement of electrons in the attached pictures.
For the first reaction:
What I think will happen is the H+ has separated from the NH3 and the OH- has bonded with the H to form H2O. Something needs to replace the OH's spot in the molecule so the NH3 will turn into NH2 and H+. The NH2 will take the OH spot while the H+ will join with the H2O to form H3O+. Is this right?
For the second reaction:
From my understanding, ethene can be hydrogenated to form ethane. However there is only 1 hydrogen available. If the double bond breaks and 1 of the carbon bonds with the hydrogen then the other carbon will not have enough electrons. Could someone give me a hint?
