- These two compounds shown go through SN1 substitution at a speed similar to some tertiary halides, even though the following compounds represent primary and secondary halides. Explain the enhanced reactivity via resonance structures and pushing arrows.What is the mechanism of the above reaction (i.e. SN1, SN2, E1 or E2)? Explain your choice in one sentence based on your answer in (i) above.The reaction below could run through both substitution and elimination reactions. 1. Provide the correct reagent to produce the products shown 2. State which mechanism(s) was followed
- Give the product of the reaction below and propose a mechanismWhen the allylic alkyl bromide shown below is heated in ethanol solvent, the major elimination product isolated is the diene shown below. A) Propose a mechanism to account for this overall transformation. Use normal curved arrows to show movement of electron pairs and be sure to draw structures for all important reaction intermediates. If an intermediate is a resonance hybrid, draw all important contributing resonance structures. B) The same alkyl bromide shown above also yields several substitution products when subjected the reaction conditions described above. Draw the structure of the major substitution product that would be isolated in the box on the product side of the reaction arrow. The second picture is for the B part of the questionComplete the reactions given below, write down the type of mechanism (SN1, SN2, E1, E2)?
- The electrophilic addition reaction shown below involves a carbocation rearrangement. For the mechanism step below, draw curved arrows to show electron reorganization. Use the arrow tool to specify the origin and the destination of the reorganizing electrons. Consult the arrow-pushing instructions for the convention on regiospecific electrophilic attack on a double bond. I understand how it's supposed to be laid out. I'm just unsure of where the first arrow comes from as there are a lot of positions. I have attached examples on what positions I mean. Thank you.Complete the mechanism for the hydrolysis below by adding any missing bonds, charges, nonbonding electrons, and curved arrows.Complete the reactions below, write the type of mechanism (S1, S2, E2).

Using the skeletal structures of the molecules, write out the skeletal structure of each reaction (don't include the mechanism). Identify what the nucleophile is in each type of reaction, especially within this SN1 reaction. Explain the reactivity of each electrophile/substrate in terms of whether they are tertiary, secondary, primary, etc. for each reaction. Include the overall chemical reaction.Several reagents and several organic structures are shown below. Construct a multistep synthetic route for the synthesis of acetylene from ethane by dragging the appropriate pieces into the bins. Note that each bin will hold only one item, and not every given reagent or structure will be used. (Stoichiometry is omitted.)
