    1. [Organic Chemistry: Requesting Help Finding a Book] I am trying to find a book for my Intermediate Organic Chemistry class. The best option would be PDF, but if that is not possible, even lower-cost used would be helpful. The university price is around $280 which is not even remotely possible for me
    2. Which book is this? And do you have any recommended books to learn university coordination compounds?
    3. Could anyone recommend me a good intro course/book?
