write three different preparations of 1,1-diphenylethanol from three different carbonyl compounds and grignard reagents
II. What carbonyl compounds and Grignard reagents would you use to make the alcohols shown below? Show all possibilities. No mechanism necessary. (8 pts) НО. b OH
Grignard reagents are used to make C-C new bonds. Their reaction with carbonyl compound leads to alcohols. However, when reacted with carboxylic acids carbonyl compounds are formed. Predict what should be the product of the reaction between 4-nitrobenzoic acid and phenyl magnesium bromide and explain in few chosen words why a carbonyl compound instead of an alcohol.
One of the most important uses for Grignard reagents is their addition to carbonyl compounds to give new carbon-carbon bonds. In this reaction, the carbon of the organometallic compound acts as a nucleophile to add to the positive carbon of the carbonyl forming an alkoxide ion intermediate. Aqueous acid is used in the second step to protonate the alkoxide ion and form the product alcohol. Draw the structure of the product(s) of step 1 when the following compound reacts with...
Which of the following Grignard reagents can be made? For the
compounds that are not feasible Grignard reagents, explain why the
compound will not work.(Include a mechanism if this would be
helpful in your explanation.)

Grignard and organolithium reagents are powerful bases. Because of this, they cannot be used as nucleophiles on compounds which contain acidic hydrogens. If they are use, they will act as a base and deprotonate the acidic hydrogen rather than act as a nucleophile and attack the carbonyl. A partial list of functional groups which cannot be used are: alcohols, amides, 1o amines, 2o amines, carboxylic acids, and terminal alkynes. Determine the product of a reaction in which one of the...
