Hi, I'm just really confused about how to explain the electrophilic and nucleophilic reactions.

Question

For instance, if you have an alkene and bromine molecules, they undergo electrophilic addition, because the alkene has an electron rich pi bond.

But do you explain the reaction by saying "the electrophile attacks the nucleophile" or do you say "the nucleophile attacks the electrophile"?

My lecture notes and my guide book says different, so i don't know if it makes a difference or how im supposed to explain it properly.

Please help! Thanks! it's for my a levels...
