- In which species (NO3- or CH3NO2) are the N-Obond(s) longer? In which species (NO3- or CH3NO2) are the N-Obond(s) weaker?Considering both 5-methylcyclopenta-1,3-diene (A) and 7methylcyclohepta-1,3,5-triene (B), which labeled H atom is most acidic? Which labeled H atom is least acidic? Explain your choices.(I) Give major products for 1,2-/1,4 additions (A) Diels-Alder (B-D) cycloadditions, [2+2] cycloaddition, and Retro-Dial-Alder (E) cycloaddition. Illustrate the regiochemistry and stereochemistry (meal, enantiomer, exo or Endo) for cycloaddition B-D.
- In 4+2 cycloaddition, ENDO stereochemistry is preferred because: endo stereochemistry allows the diene to adopt s-cis conformation. endo stereochemistry results in less steric hindrance. the transition state leading to endo stereochemistry is higher energy. it allows for additional π to π overlap between the diene and the dienophile.Can someone draw the arrows for this reaction so I can understand how the product was formed? I'm having trouble understanding that aspect of the Diels-Alder reaction.Considering both 5-methylcyclopenta-1,3-diene (A) and 7-methylcyclohepta-1,3,5-triene (B), which labeled H atom is most acidic?Which labeled H atom is least acidic? Explain your choices.
