Interpretation:
A reaction roadmap have to be made for the reactions in the study Guide section of chapters 6-11.
Concept Introduction:
Markovnikov addition: The addition reaction of parotic acids to a different alkene or alkyne, the hydrogen atom of
Anti-Markovnikov addition: These rules describe the regiochemistry where the substituent is bonded to a less substituted carbon, rather than the more substituted carbon. This placed is quite unusual as carbon cations which are commonly formed during alkene or alkyne reactions tend to favor the more substituted carbon.
Unsaturated compound: The nucleophile reacts with
The alkylation at the β carbon of ketone or aldehyde is done by the following mechanism;
(1) Alkylating the β carbon via enamine intermediate.
(2) Alkylating the β carbon via a Michael reaction.
Osmium tetroxide
The reaction mechanism involves the concentrated addition of the osmium tetroxide to the
Lindlar catalyst: The catalyst is used for the hydrogenation of
Ozonolysis Reaction: It is an oxidative reaction which is used to oxidize the carbon-carbon double and triple bond.

- 3) A common practice that organic chemists work on is a process known as retrosynthesis. In this a chemist will take known reactants and devise a synthetic pathway to produce the desired products using reactions that they know. As you proceed through organic chemistry you will be tasked with thinking about this process. How would you make the desired final product starting from the alkyne. It will take a couple of reactions. Please show the reagents necessary. And for your last step please show the arrow pushing. Starting material Br Product Br ...arrow_forward1. What are the general instructions before, during, and after experiment, especially in organic chemistry? What are the dos and don’ts in the laboratory? 2. A BSES student, Christian, is working in an organic laboratory for the experiment on the organic synthesis without the guidance of his superlatively handsome instructor, Arwil Nathaniel Alfonso ©. He prepared five organic solvents: 1-pentanol, 2-pentanol, 2-pentanone, benzaldehyde, and m-cresol but he didn't put any label in any of these. Meanwhile, Ryan used the solvents she prepared and placed back in different order. Knowing Christian would punch Ryan in his digestive tract because there is a possible explosion. Prepare a systematic flow chart of qualitative tests to help Ryan to label the solvents before Christian used the organic solvents. 3.

- Alcohols are acidic in nature. Therefore, a strong base can abstract the acidic hydrogen atom of the alcohol in a process known as deprotonation. The alcohol forms an alkoxide ion by losing the proton attached to the oxygen atom of the hydroxyl ( -OH) group. The alkoxide formed can act as a base or a nucleophile depending on the substrate and reaction conditions. However, not all bases can abstract the acidic proton of alcohols and not all alcohols easily lose the proton. Deprotonation depends on the strength of the base and the acidity of the alcohol. Strong bases, such as NaNH2, can easily abstract a proton from almost all alcohols. Likewise, more acidic alcohols lose a proton more easily. Determine which of the following reactions would undergo deprotonation based on the strength of the base and the acidity of the alcohol. Check all that apply. ► View Available Hint(s) CH3CH,OH + NH3 →CH,CH,O-NH CH3 CH3 H3C-C-H+NH3 → H3 C-C-H OH O-NH CH3CH2OH + NaNH, → CH3CH,O-Na* + NH3 CHC12 Cl₂…arrow_forwardFirst, draw your chosen compounds including any non-bonding electrons and non-zero formal charges Circle and name any pH-sensitive functional groups. Choose an organic solvent that will dissolve both or your compounds and an aqueous solution (i.e. conc. aqueous NaOH, 5% aq. NaHCO3, or 3M HCl) that would successfully separate the two compounds selected.arrow_forward1. Synthesizing an organic molecule. Organic chemists are molecular architects that build organic molecules through planned syntheses and use chemical reactions to describe complicated biochemical pathways. The point of this exercise is to be creative and plan out a multi-step synthesis to build any molecule your synthesis needs to satisfy the following criteria: -Use propyne as a starting material -Includes at least 4 different reactions with specific conditions given (i.e., reagent and solvent). -Must include converting your molecule into following functional groups at some point in the planed synthesis: an alkyne, a carboxylic acid derivative, an amine, and an aldehyde or ketone. You may include other functional groups, but these are the minimum. -Must make at least one C-C bond in the synthetic route. -Must include detailed arrow pushing mechanisms for each proposed step.arrow_forward
