level questions: addition reactions of alkenes
Question | Answer |
---|---|
what are the conditions for a hydrogenation reaction to take place | temp of 150, nickel catalyst |
what is a hydrogenation reaction | alkene + hydrogen --> alkane |
what are the conditions for a hydration reaction to take place | water must be in the form of steam, temp of 300, phosphoric acid catalyst, 70 atm |
what is a hydration reaction | alkene + steam --> alcohol |
how would you increase the yield of alcohol in a hydration reaction | the reaction is reversible so unreacted alkenes and steam are passed back through the phosphoric acid catalyst |
what is a halogenation reaction | alkene + halogen --> di(halogen)(alkane) |
ethene + bromine --> | dibromoethane |
ethene + iodine --> | diiodoethane |
dichloropropane --> | propene + chlorine |
what reaction is this an example of | hydration reaction |
what reaction is this an example of | hydrogenation reaction |
