Label the following compounds as aromatic, anti-aromatic, or non-aromatic (assume that all molecules are planar). ✪ ✩ Predict the product that would be formed when biphenyl reacts with a mixture of nitric and sulfuric acid. Draw a detailed, step-wise mechanism that shows formation of the electrophile and explains the observed regiochemistry. HNO3 H₂SO4

Arrange these compounds in increasing order of reactivity in SN2 nucleophilic substitution?

20:33 1 : ●●● all the proper notations for depicting resonance. 4. Provide the full mechanism (curved arrows and intermediates) that leads to the product in the scheme below. Draw the structure of the product to help you see how the starting materials will combine. Use that as a clue to figure out how to draw the mechanism arrows. ccare in your scheme. Be sure to use NaOEt 00 i 5. Provide the major organic product of the reaction shown. Determine if these conditions are best for SN2, SN1, E2, or E1. Be sure to indicate stereochemistry by using the proper wedges/dashes in the product. acetone phenyl butanoate Send a chat O
