Question
Chapter 7, Problem 61P
Interpretation Introduction
Interpretation:
The result of the dissolution of maleic anhydride in freshly distilled cyclopentadiene should be given.
Concept introduction:
Diels–Alder reaction:
- It is a [4 + 2] cycloaddition reaction between conjugated diene and dienophile which forms a substituted cyclohexene.
- There are no intermediates in the reaction and it is a one step process.
- Diene will be a compound with conjugated double bond.
- Dienophile is a substituted
alkene oralkyne .

- In an experiment, triphenylmethanol is prepared using the Grignard reaction. 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.
