Give the major product(s) of the following reactions, if there is a reaction. For electrophilic aromatic substitution, assume that only one equivalent of the electrophile adds to the aromatic ring (monosubstitution). However, there may be more than one product formed. 12, H2O2 H2SO4 HO. CH3 1) CI AICI3 2) H20 O,N. Br2 FeBr3

Complete the following reaction schemes. Some may take more than one step and some may have several routes to the product.

Can someone help me with these and explain how they did it? The question is to predict the major organic product of each reaction.

Which of the following compounds is LEAST reactive in aromatic nitration reactions? I O A. II OB. III OC. I OD. IV. Br III note: NO₂ = NO₂ IV 0 US

9. What will be the site that leads to the major mono product for an electrophilic aromatic reaction of the following compound? substitution substitution A. I B. II C. III D. IV IV NO₂ NHCOCH3

NBS, hv Br Br Compounds II and II Compound II only O Compound I only O Compound II only A Moving to another question will save this response O O C

There could be one or more than one answer. Please help.

Answer the following questions. + 2 H20 + H3O* + CIF a. Complete the mechanism below with the missing structure and arrows. Identify any acids, bases, electrophiles and nucleophiles. CI + H20 + H20 + H3O* + ci HO, +0-I

Draw visual representations of the steps below... 38. Follow the following reaction steps. Step 1: Identify the functional groups in the molecule below. Step 2: React the molecule above with NaBH4. Step 3: React the product in Step 2 with an acid catalyst (protonation) of the remaining carbonyl group. Step 4: Show intramolecular ring closure, followed by methoxy group leaving. regeneration of the carbonyl group, and loss of proton to methoxy group to make metha...

3. SN2 reactions are useful in the synthesis of many pharmaceutical compounds. The antiviral agent acyclovir can be prepared using an S№2 reaction as shown below followed by a hydrolysis reaction. The hydrolysis reaction will be discussed in CHEM 40B. R'RN A + B SN2 R'RN ELECTROPHILE: من مهمه NUCLEOPHILE: Identify which molecule (A or B) would serve as the electrophile and which would serve as the nucleophile in the S№2 reaction. Place your responses in the box below. Connections to biology The amino acid cysteine is one of the common building blocks of proteins that contains the thiol (SH) functional group. The reactivity of the thiol group allows researchers to connect various molecules to proteins, a process known as labeling. For example, it is possible to connect fluorescent probes that allow us to trace the fate of proteins in the cell. H SH O Cysteine amino acid within a protein chain sa acyclovir LG H₂N S OH H O Cysteine amino acid labeled with electrophilic probe…
