(ME EX1) Prblm #9/10
Can you explain in detail (step by step) I'm so confused with these problems. For turmber 13 can u turn them into lewis dot structures so I can better understand because, and then as well explain the resonance structure part. Thanks for the help.
Problems 19 and 20: (ME EX1) Can you please explain the following in detail? I'm having trouble understanding them. Both problems are difficult for me to explain in detail, so please include the drawings and answers.
