can someone explain resonance structures to me?

[steppingstone]

I've watched chad's 2x for resonance but I've never been able to get a hold of this topic. Especially in question 103 in OC destroyer. I just don't know what i'm comparing it to. Any help would be great

Resonance is this concept how electron clouds are distributed across the whole molecule, something that 2D representations of 3D molecules fail to capture. You do not need to know this that much for the DAT. Just know benzene and how it reacts as well as 1,2 and 1,4 additions. Good luck!

it reacts 1,2 addition with cold temperatures like -40 degrees and is kinetic and 1,4 in warm temps? (Destroyer, I love you haha)

Just remember not to break an octet or a single bond. Also, keep the overall charge constant at all times. Lastly, just move electrons, not atoms. So, if you can go from a lone pair to a double or triple bond, or vise versa and keep all the rules, you will be fine.
Hope this helps. Good luck.
