Our lecturer just finished the first chapter of Organic Chem. He explained things like the spdf electron distribution thingies, then he taught us how to draw lewis structures and he introduced some formula for finding an atom's charge before doing it on lewis, then he told us after hybridization, and the angles at which bonds occur and we had to specify the type of hybridization/bond (this bond is between sp3 sp3 etc)
Then, we finished off the first chapter by studying skeletal structures (drawing lines for C-C bonds, ignoring C-H bonds and so on)
Can someone tell me how can I recap all that shit? We don't have slides, and I didn't write down the notes.
