Practical: Haloalkane Reactivity Flashcards
1
Q
What is the ewauation for haloalkane + water
A
Haloalkane + water -> alcohol + HX
2
Q
What is the ionic equation for the AgNo3 + haloalkane
A
Ag+ + X- x> AgX(s)
3
Q
Method:
A
Set up 3 test tubes
Add the same amount of different haloalkanes
Add ethanol
Add AgNO3(aq)
Time how long it takes for the precipitates to form
4
Q
What precipitate does iodine form
A
Yellow
5
Q
What precipitate does bromo form
A
Cream
6
Q
What precipitate does chlorine form
A
White
7
Q
What is the order or precipitate formation
A
Iodo = fast
Bromo
Chloro = slow
8
Q
How do u make it a fair test
A
Make all haloalkanes have the same carbon skeleton (branching and length)
9
Q
Why is iodo hydrolysed the fastest
A
It was the lowest bond enthalpy
As it is the least electronegative
