Please help answer questions. Thank you! 1. A) Why is the C=0 stretch in the IR so much stronger than the C=C stretch of a simple alkene hydrocarbon (2 points) B) Why is the CNC stretch of 1-methoxy-1-propeneso much stronger than the CNC stretch of 1- butene. Justify your answer with the use of a resonance structure. (2 points). C) Explain why the C=0 stretch of 1-butanal requires more energy (higher frequency) than the CEO stretch of acrolein.
