Is this chemical pathway correct?
I am trying to get ethylamine from ethene.
Ethene + Chlorine gas = 1,2 - Dichloroethane
1,2 - Dichloromethane + Hydrogen gas = Ethane
Ethane + Ammonia = Ethylamine
Thank you

Why not just ethene + h2 = ethane?
When making an alkane into an alkene you must substitute a chlorine as a intermediate because alkanes are not that reactive. However, the double bond in alkenes allow for easy reactions thus the chloro buffer is not required

Remember the Pt / Ni / (Pd/C) catalysts for hydrogenation of alkenes.

Both of these are wrong I think. Do you mean ethene +chlorine gas =1,2-dichloroethane;
Also I'm pretty sure you can go directly from ethene to ethylamine by adding ammonia with an appropriate catalyst not sure what exactly.
But you could add water with the catalyst H3PO4 to get ethanol and then add ammonia with a catalyst of an oxide - dichromate ions or something to get ethylamine.
Edit: There's no such thing as 1,2-dichloromethane...
