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.

Shown below on Fischer projections are two enantiomeric alcohols. What alkene and what reagents would yield these alcohols upon reacting with each other? Complete the alkene template below to show the structure of the alkene and provide the required reagent(s) by writing it/them above/below the reaction arrow.

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...
