For the given SN2 reaction, draw the organic and inorganic products of the reaction, and identify the nucleophile, substrate, and leaving group. Include wedge-and-dash bonds and draw hydrogen on a stereocenter. HI.... + CI Draw the organic product. :C=N to H Organic product + Inorganic product Draw the inorganic product. ū

Tributyltin hydride (Bu3SnH) is used synthetically to reduce alkyl halides, replacing a halogen atom with hydrogen. Free-radical initiators promote this reaction, and free-radical inhibitors are known to slow or stop it. Your job is todevelop a mechanism,

Predict the major products of both organic reactions. Be sure to use wedge and dash bonds to show the stereochemistry of the products when it's important, for example to distinguish between two different maje products. B **** :0 + I H₂O 5 Click and drag to start drawing a structure.

Determine the mechanism (SN1, SN2, E1, or E2) and major product for the reactions below. Consider the type of LG (primary, secondary, or tertiary) AND the reactant type (strong nucleophile, weak base, weak/hindered base) to determine the correct mechanism/product!

H₂C H H₁C Br NBS CH, CH₂ CC, hv **You may assume that Br-Br is formed by a side reaction that occurs (which we discussed in class). This is useful for one of the steps of the mechanism.

Draw the structure of the product of the Michael reaction between propenamide and diethyl malonate

please do the mechanism. Identify which one is the nucleophile/electrophile. Name the reaction as well.  Discuss the stereochemistry so why the dash bond go to wedged- due to inversion? Why is PPh3 used for selectivity ? Please answer all of my questions.

• Same reagents as acid-catalyzed dehydration, except starting with a instead of an alcohol. • Same as the general mechanism hydrohalogenation, except with . Remember that EVERY acid-cat. mechanism begins with General Reaction: EXAMPLE: Provide H₂O H₂SO4 EXAMPLE: Provide the mechanism for the following addition reaction. H₂O H₂SO4 OH WH H₂O H₂SO4 as the nucleophile and ends with do PRACTICE: Provide the mechanism and predict the product of the following reaction. MAXO

Please answer this organic chemistry question: show all three steps and radical mechanism for hydrobromic acid in peroxide reacting with 3-methylene-2-ene. Are there multiple products?   Background information just in case needed for the intial question above ? but if not needed  just ignore this background information: which of the following compounds will react the quickest? A) Fluorine with a tertiary radical  B) chlorine with a tertiary radical  C) Bromine with tertiary radical  D) chlorine with a primary radical  E) bromine with a primary radical

Provide steps to further clarify and asure undertanding on topic.

urgent pls help answer both questions

What is important about this slide？ what is reactant and what is product？what reactant to give what？what principle is important here？what does it means that acetal can not be reduced？which one is acetal？ explain the mechanism please？ Lable out which is reactant and which is product please. I am totally confused

Show the three step mechanism to form the major product only for the radical bromination shown below. label the initiation, propagation, and termination steps. draw the FULL electron pushing mechanism with ALL intermediates, lone pairs, and formal charges clearly labelled. Show ALL electron pushing arrows and label the nucleophile and electrophile where appropriate for non-radical mechanisms.

Fill the blank space.  Compounds containing a phenol group may work as ANTIOXIDANTS to prevent free radical damage.  This is accomplished when a free radical (or UV light) encounters a phenol group, turning the phenol group into a radical.  However, contrary to typical radical behavior, the structure of the phenol radical can neutralize (or quench) the unpaired electron.  Specifically, the phenol structure neutralizes (or quenches) the unpaired radical electron by doing the following: taking the electron and ---------.  The correct name (or abbreviation) of an example compound containing a phenol group with antioxidant properties is: ---------.

Draw the least stable resonance form for the intermediate in the following electrophilic substitution reaction. CF3 CF3 Br₂ / FeBr3 Br • 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. 0▾ 99.85 / 4 0 √n [ ?

As we will learn, many antioxidants–compounds that prevent unwanted radical oxidation reactions from occurring–are phenols, compounds that contain an OH group bonded directly to a benzene ring.a.) Explain why homolysis of the O–H bond in phenol requiresconsiderably less energy than homolysis of the O–H bond in ethanol(362 kJ/mol vs. 438 kJ/mol).b.) Why is the C–O bond in phenol shorter than the C–O bond in ethanol?
