Reactions of Haloalkanes Flashcards
Why are Haloalkanes fairly reactive?
Due to the polarity C-X. Due to this polarity of the functional group, this results in an overall permanent dipole making these molecules polar.
What are the general formula Haloalkanes?
CnH2n+1X
Why are substitution reactions in haloalkanes faster?
Due to the added polarity of the C-X bond.
What happens during a substitution reaction in Haloalkanes?
When the solvent is water, the substitution reaction mechanism predominates, and in the presence of a strong base eg. NaOH or KOH, the haloalkane.
How does the attacking work in a haloalkane reaction?
The attacking series can be either the lone pair on a species like H2O or OH- and attacks a positive side of a polar bond. (The effect is to substitute the halogen with the attacking species)
What happens during a Haloalkane elimination reaction?
When the solvent is alcohol, a different process causes the elimination of H-X to be favoured.
What is the result of Haloalkane elimination reaction?
An alkene is formed.
What is the name of this type of reaction?
Dehydrohalogenation.
