Identify ALL products expected from this reaction. Bonus question (for class): Draw the products expected if water were added instead of CH2Cl2 Br2 CH2Cl2

Fill in the missing structure(s) for the reaction pathways shown below. Provideall starting material(s), reagent(s), or product(s). If more than one product can beformed, draw all major products. If more than one starting material or reagent ispossible, write all starting materials or reagents. Include stereochemistry in youranswer, if applicable, and draw all stereoisomers. Don't forget about resonance.

A E OH OH H This is a(n) OH R B F PCC, CH₂Cl₂ H type reaction. The major product if R = CH₂CH3 is compound The major product if R = H is compound G Look at the given reaction and use the letter code corresponding to each compound in the blank to indicate the expected product(s), or fill in the blank with the appropriate vocabulary word or phrase. If a specific stereoisomer (e.g single enantiomer) is formed, select that isomer only. If a mixture of stereoisomers (e.g. racemic or diastereomers) is formed, select the single structure that shows the appropriate mixture (e.g. lines not dashes). If we convert the reagent to Na2CrO4, H₂SO4, H₂O: The major product if R = CH₂CH3 is compound The maior product if R = H is compound ??? OH D H H though compound

Draw the corresponding reaction coordinate diagram for (Rx 2) and clearly label the starting material (SM), the product (Pdt), the transition state (TS), the enthalpy (AHº) and the energy of activation (La). (Note: RX 2 is an EXERGONIC reaction). Br Free Energy B Rx 2 Q + Br Reaction Progress of Rx 2

The carbocation intermediate formed in the first step is resonance-stabilized. Draw the other resonance structure (by modifying the provided drawing) and add curved arrow(s) to convert the first resonance structure into the second one. Use the +/- tools to add/remove charges, and use the single bond tool to interconvert between double and single bonds. ÇH3 CH3 H3C. H,C. CH3 CH3 ČH3 ČH3 ČH3 ČH3 Edit Drawing

Draw the remaining product of the reaction.

Draw the structure of the major organic product of the following reaction. CH3 CH3CHC=CH₂ CH₂CH3 progress 1. Hg(OAc)2, H₂O 2. NaBH4 • You do not have to consider stereochemistry. • In cases where there is more than one answer, just draw one. [ ] در -Sn ChemDoodleⓇ®

Draw the strcutres of the missing reactants, intermediates, or products in the following mechanisms. Include all lone pairs.

Provide the correct IUPAC name for the skeletal (line-bond) structure shown here. Stereochemistry is ignored. 2,2,4-tri methyl-3-pentene Incorrect, 1 attempt remaining You have incorrectly numbered the parent chain. Number the carbons of the parent chain so that the carbons of the alkene functional group have the lowest possible numbers, taking priority over the alkyl substituents.

a) b) C) Show the steps necessary, in order, to make each of the following compounds. Start with benzene, and use only reactions we studied this semester. O 10₂ NO₂ -ECH₂CH3 o Br
