I need help with writing word equations for all these, and also classifying the reactions.

1. but-1-ene + bromine
2. pent-2-ene + hydrogen bromide
3. 2-methylpent-2-ene + chlorine
4. 2.3-dimethylbut-2-ene + bromine
5. pentane reacting with 1 molecule of chlorine
6. hexane reacting with 1 molecule of bromine
7. but-2-ene reacting with potassium permanganate

Any help would be great thanks!

alkene + halogen --> free radical addition
alkane + halogen --> free radical substitution

What about electrophilic addition?

What about electrophilic addition?
a halogen is a free radical since it has an unpaired electron.
--------------
Electrophilic addition involves the attack of a positively charged species, i.e. HBr, H+.

...or a carbocation as formed as an intermediate in the electrophilic addition mechanism?
