(9 cards)
1
Q
Functional group of a haloalkane
A
-F, -Cl, -Br, -I
2
Q
Describe and explain the polarity of the C-X bond
A
Polar, the halogen is more electronegative so gets a δ− charge
3
Q
Describe and explain the strength of the C-X bond
A
C-X enthalpy increases down the group.

A
Nucleophilic substitution
Excess ethanol ammonia
7
Q
How do CFCs damage the environment
A
Breakdown of ozone by radical, due to the UV light
8
Q
Three equations to show breakdown of the ozone layer by CFCs
A
Cl * + O3 > ClO * + O2
ClO * + O > Cl * + O2
Overall - O3 + O > 2O2
