A Moving to another question will save this response. Question 5 Which one of the following compounds does not undergo a Friedel-Crafts reaction? (remember: limitations to this reaction O toluene O benzene O chlorobenzene O nitrobenzene O t-butylbenzene A Moving to another question will save this response.

Your Name: 1. Consider the Diels-Alder cycloaddition reaction below. D + heat D H D = deuterium = 2H Draw the major regioisomer (or in other words, constitutional isomer) expected to form. Draw appropriate resonance structures and explain why only one constitutional isomer is expected to form. Discuss if this can be drawn with both groups on the dieneophile being endo or one has to be endo and the other has to be exo.

2. Fill the missing reagents or products for the incomplete reaction schemes shown below (only Reagent A or Reagent B will react in significant quantities). F (1 mmol) Reagent A (1 mmol) Reagent B (1 mmol) Major Product from Reagent A Major Product from Reagent B Explain the selectivity observed in this reaction using words and drawings. Br NaNH2 Br NH3, -35 °C Вrz, FeBr3 Draw the mechanism for the transformation shown above. Be sure to draw the important resonance structures that account for the regioselectivity observed in this reaction.

Draw the most stable resonance form for the intermediate in the following electrophilic substitution reaction. CH3 CH3 H3PO4 HO, + H3C CH3 HO HO First stage in synthesis of the epoxy and polycarbonate ingredient bisphenol-A You do not have to consider stereochemistry. Include all valence lone pairs in your answer. In cases where there is more than one answer, just draw one.

For each compound predict if it's positive or negative for AgNO3/EtOH Test (SN1), propose 1 sentence explanation why. 2-Bromobutane 1-bromobutane 2-Chlorobutane 1-chlorobutane t-butyl chloride benzyl chloride bromobenzene bromocyclohexane bromocyclopentane

The two alkenes below react with HI at different rates. CH3CH=CHCH3 and CH₂=CH₂ Draw the structural formula of the MAJOR product formed by the alkene having the HIGHER reaction rate. • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one.

Step 6: Now that you have determined the substrates and mechanism of a Diels-Alder reaction, you will learn how to recognize when you should use the Diels-Alder reaction. In a synthesis reaction, if you are given a cyclohexene product with no other obvious functional group transformations and an electron-withdrawing group two carbons away from the alkene, it is likely made via the Diels-Alder reaction. Deduce the structures of the starting materials to form the Diels-Alder adduct shown. ..... CN CN Diene + Dienophile

bromobenzene Leaving Groups: Which will undergo a faster SN2 reaction: 2-bromobutane or 2-chlorobutane? Which will undergo a faster SN1 reaction: 2-bromobutane vs. 2-chlorobutane? Provide an explanation for the above predictions. Solvent: drop
