Organic Chemistry
What is the first step in the electrophilic aromatic substitution mechanism?
Given the following compounds: benzene, pyrrole, furan, and thiophene, arrange them in order of increasing reactivity in EAS reactions.
Which resonance structure contributes most to the stability of the intermediate during EAS at carbon 2 in furan?
Which product is expected to be the major product in the EAS reaction of thiophene with bromine?
Predict the major product when furan undergoes EAS with acetic anhydride.
