Concept explainers
Interpretation:
The major product resulting from each of the given competition experiments is to be predicted.
Concept introduction:
Nucleophilic substitution happens by two different mechanisms:
The
In the rate determining step, leaving group generates a carbocation intermediate.
Carbocation intermediated then undergoes a rapid reaction with nucleophile.
The
In the rate determining step, nucleophilic approaches the carbon from the side directly opposite to the leaving group.
The

All of the carbon atoms of the target molecule must be derived from ethylene. Show all intermediate molecules synthesized along the way.arrow_forward
- Alcohols are important for organic synthesis, especially in situations involving alkenes. The alcohol might be the desired product, or the OH group might be transformed into another functional group via halogenation, oxidation, or perhaps conversion to a sulfonic ester derivative. Formation of an alcohol from an alkene is particularly powerful because conditions can be chosen to produce either the Markovnikov or non-Markovnikov product from an unsymmetrical alkene. Using your reaction roadmap as a guide, show how to convert 4-methyl-1-pentene into 5-methylhexanenitrile. You must use 4-methyl-1-pentene and sodium cyanide as the source of all carbon atoms in the target molecule. Show all reagents needed and all molecules synthesized along the way.arrow_forwardBoth blanks options are samearrow_forward1) Provide an arow-pushing mechanism for the reaction shown below. 8 H3O+ (aq)arrow_forward

The Grignard reaction involves preparation and reaction of a very nucleophilic organo-magnesium compound. The Grignard reagent is very reactive and is easily destroyed by reaction with atmospheric water, oxygen, or carbon dioxide. The Grignard reagent must be prepared under strict anhydrous conditions (dry glassware, dry solvent). The volative solvent, diethyl ether, helps to prevent oxygen or carbon dioxide from entering the reaction vessel. Reaction of bromobenzene with magnesium in ether produces phenylmagnesium bromide. This Grignard reagent then reacts with methyl benzoate to produce the corresponding alkoxide. Reaction of the alkoxide with aqueous acid then produces the alcohol. Why does pressure develop when the separatory funnel containing aqueous sulfuric acid and the ethereal solution of organic products is shaken?arrow_forward
