Number of collisions per second |
|
|
Concentration |
Number of particles per mL
Number of collisions per second |
|
|
Temperature |
more energy more particles have sufficient energy to react more successful collisions per second
move faster number of collisions per second |
|
|
Catalyst |
lowers the activation energy without being used up
more successful collisions per second |

|
|
Solubility: add water
Insoluble |
All other functional groups - 2 layers
(i.e. not alcohols, amines and carboxylic acids) |
|
|
Add Br2 - addition |
orange --> colourless - alkane (rapid) UV orange --> colourless - alkane (slowly) |
|
|
Add Br2 - substitution |
stays orange - alkane (no UV, short time) - all other functional groups |
