Reactions Flashcards
Understand and explain reactions
Homolytic
When a molecular bond breaks and each fragment keeps one of the original electrons.
Heterolytic
When a molecular bond breaks and one fragment keeps both of the original electrons.
Directly dependent on electronegativity.
Hydrogenation
A chemical reaction between H2 and another compound. A catalyst of Pd/C is used.
Hyrdohalogenation
A reaction between H-(Br, Cl) and a compound. It forms a carbo-cation and a halogen anion. The halogen anion then inserts itself onto the carbo-cation, forming the new structure.
Hydrobromination and Hydrochlorination are the only reactions that can occur.
Hydration
A reaction where water is added across a carbon-carbon double bond. It forms an alcohol by breaking the pi bond and attaching a hydrogen and hydroxyl group to the carbons involved.
Polomerization
A chemical reaction that joins monomers together to form larger molecules called polymers.
Posion Hydrogenation
Hydrogenation with Lindars catalyist. Lindars catalyist is Pd, PbR3N. The N has 2 e- on top of it.
Hydration of Alekenes
Add’s a OH group to the most substituted carbon. Reactants- H2O, H2SO4
