- Which or which of the following molecules are aromatic, antiaromatic or non-aromatic?arrow_forwardwhich molecules should be aromaticarrow_forwardQuestion (Organic Chemistry) Consider molecules A–D. Does the arrow pushing in each structure leadto an acceptable resonance form? If so, explain why it is acceptable or unacceptable? What are the rules and logic? If so, draw it and carefully explain your answer and provide explanations for why each structure leds to an acceptable or unacceptable resonance form. Why is the arrow pushing acceptable or unacceptable in each individual case? Explain you answer with many details, logic, and in a step-by-step fashion.arrow_forward
- Question (Organic Chemistry) Consider molecules A–B. Does the arrow pushing in each structure leadto an acceptable resonance form? If so, explain why it is acceptable or unacceptable? What are the rules and logic? If so, draw it and carefully explain your answer and provide explanations for why each structure leds to an acceptable or unacceptable resonance form. Why is the arrow pushing acceptable or unacceptable in each individual case? Explain you answer with many details, logic, and in a step-by-step fashion. Please explain your rationale or logic. The answers provided on Bartleby lack a clear rationale and explanation of why the octet rule matters or why electron rich and electron deficient sites are important to this drawings.arrow_forwardUse Huckel’s rule to identify if its aromatic or not. Draw the resonance structure of the ff. compounds. note: I need the answer immediately. I will send a good rate right away as well.arrow_forwardare these aromatic, antiaromatic, or nonaromatic?
