- a) The alkene drawn here undergoes an electrophilic addition reaction with HBr. Ś i) Give the IUPAC name of this molecule. ii) Outline the mechanism of this reaction. Your mechanism should show the formation of BOTH possible products and should also name both products. iii) Explain why the Markovnikov rule does not predict a major product in this case. b) The common name of the molecule drawn below is diisopropyl ether. Its structural formula is (CH3)2CHOH(CH3)2. tot It can be synthesized in two steps using the starting materials propan-2-ol, 2-chloropropane and sodium metal. One of these steps is a nucleophilic substitution reaction. i) Using structural formulae, write two balanced chemical equations representing the two steps of this synthesis. No state symbols are required. ii) Outline the mechanism of the nucleophilic substitution step.arrow_forwardDraw the structure of the product in the reaction. Draw applicable formal charges and the appropriate number of hydrogens on the nitrogen atom.arrow_forward(a) Which of the following has lone pair on O atom that is part of aromaticity? (b) Which lacks complete cyclic conjugation? (c) Which does not follow the Huckel rule?arrow_forward
- Can you explain how an alkene bonds to a metal like in this compound using some orbital diagrams?arrow_forwardWhich of the following resonance structures has the greatest contribution to the hybrid? Explain.arrow_forwardClassify each of the following compounds as aromatic, anti-aromatic, or non-aromatic. Assume all rings are planar (Please explain)arrow_forward
- Question: How does the introduction of a substituent group on a benzene ring affect the aromaticity and reactivity of the compound?arrow_forwardOne possible isomer created by a substitution reaction that replaces a hydrogen atom attached to the aromatic ring of toluene with a chlorine atom is shown here. Draw two other possible isomers in which the chlorine atom replaces a different hydrogen atom attached to the aromatic ring:arrow_forwardBr No reaction occurs when benzene is treated with Br, in CCI4. When anthracene is treated with Br, in CCI4, however, then addition of Br, occurs, as shown here. Explain why. Br2 CCI4 Anthracene Brarrow_forward
