Haloalkanes Flashcards
When alkenes react with halogens what needs to be present
Uv light
What are the 3 stages of free radical substitution reaction
Initiation
Propagation
Termination for
Give the equation when cl free radicals react with oxygen in the ozone
Cl. +O3->ClO. +O2
ClO.+O3->2O2+Cl.
What is a nucleophile
An electron rich species that are negatively charged it’s an electron pair donor
Give 3 common nucleophiles
CN cyanide
Hydroxide ion
Ammonia NH3
With haloalkanes what type of reactions do nucleophilles undergo
Nucleophile substitution
When cynaide reacts with a haloalkane what conditions are needed and what is formed
Ethanolic
Warm
A nitrile is formed
When hydroxide ion and haloalkane react what conditions are needed and what is formed state the reaction name
Aqueous Naoh
Warm
Ethanolic (solvent)
An alcohol
Hydrolysis
When ammonia and haloalkanes react what conditions are needed and state what’s formed
Conc amonnia dissolved in ethanol
A is primary amine is formed
When will a reaction between OH and haloalkane be nucleophillic elimination and what is formed
When the conditions
Are hot and ethanolic
A alkenes is formed
In nucleophillic elimination state the role of the hydroxide ion
It acts as a base
Which haloalkane reacts the fastest and why
C-I
This is because it has the weakest bond and so it’s bond enthaply is less meaning it can be subs
