Heat below 110 degrees
2
Q
Name a reagent and condition for the hydration of alcohols
A
- potassium dichromate
- heat
3
Q
What happens in an elimination reaction?
A
HX (when x is halogen) is removed from hydrocarbon chain and double bond is formed
4
Q
Why must NaOH be dissolved in alcohol is its used as a reagent in an elimination reaction?
A
To avoid a substitution reaction from occurring
5
Q
What distinguishes an elimination reaction
A
An Alkene (with double bond) is formed \+HX (when x= halogen)
6
Q
Where does an electrophilic addition occur
A
A region of high electron density (pie bond/double bond —> single bond)
