1
Q
What is the role of the OH- in elimination reactions?
A
It acts as a base, producing an alkene
2
Q
What is concurrent substitution and elimination?
A
When haloalkanes react with hydroxide ions and both elimination and substitution happen at the same time
3
Q
What conditions are favoured by substitution?
A
Warm, dilute aqueous sodium hydroxide or potassium hydroxide
4
Q
What conditions are favoured by elimination?
A
Hot, concentrated ethanolic sodium or potassium hydroxide
5
Q
What type of haloalkane is favoured by substitution?
A
Primary haloalkanes
6
Q
What type of haloalkane is favoured by elimination?
A
Tertiary haloalkanes
