(a)
Interpretation:
The transformation from the given starting material to the target molecule must be shown along with Retrosynthetic analysis.
Concept Introduction :
A Retrosynthetic analysis helps to find out the suitable starting material for a target molecule synthesis. Thioether can be synthesized following
(b)
Interpretation:
The transformation of the target molecule must be shown along with Retrosynthetic analysis.
Concept Introduction :
A Retrosynthetic analysis helps to find out the suitable starting material for the synthesis of a target molecule. Williamson ether synthesis follows the SN2 pathway in which sodium alkoxide and alkyl halide are used.

- Select the conditions in which elimination/condensation is most likely to occur. Note that only one of these needs to be present for elimination/condensation to be likely. Protic solvent Aprotic solvent Acidic conditions Basic conditions Cold Hot Shorter reaction time Longer reaction timearrow_forwardComplete the mechanism for the formation of the major species at equilibrium for the reaction of butanal in methanol solvent and catalytic aqueous acid. Make sure to include any missing atoms, bonds, charges, nonbonding electrons, and curved arrows.arrow_forwardGive two possible [1,2]-rearrangement products where an alkyl group migrates in the following compound. Motivate also which of the two products will be formed preferentiallyarrow_forward
- 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.)arrow_forwardSynthesise the target molecules drawn below using precursor chemicals within the following limitations: 1) ALL intermediates and reagents must be shown.2) Each molecule requires multiple step synthesis.3) You must also synthesize any organometallic reagents or ligands that you wish to use. b) Use any precursor molecules with 7 carbon atoms or less.arrow_forwardNonearrow_forward
- Provide a synthetic pathway for the following transformation and draw intermediate structures. The overall process can be performed in less than 6 stepsarrow_forwardSeveral reagents and several organic structures are shown below. Construct a multistep synthetic route from the reactant 2-methyl-1-butene to the product 3-bromo-2-methyl-2-butanol 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.arrow_forwardSynthesise the target molecules drawn below using precursor chemicals within the following limitations: 1) ALL intermediates and reagents must be shown.2) Each molecule requires multiple step synthesis.3) You must also synthesize any organometallic reagents or ligands that you wish to use. a) Aspirin is a common pain killer that was developed by Bayer.arrow_forward
- Modify the given structure and the product formed.arrow_forwardIn a Wittig reaction, a ketone or aldehyde reacts as an electrophile with a nucleophile called a Wittig reagent (or phosphonium ylide) to produce an alkene. The Wittig reagent is commonly synthesized first in a two-step process beginning with an alkyl halide, then reacted with the carbonyl compound. In this problem, you'll explore the mechanism of a multi-step synthesis to make an alkene using the Wittig approach.arrow_forwardwhat is a multistep synthesis for this transformation. add any reagents or compounds to help accomplish itarrow_forward
