The equation for the reaction of benzaldehyde (C7H6O) with methanol (CH4O) to give benzaldehyde dimethyl acetal (C9H12O2) and water is given below. A catalyst is also used in the reaction but does not affect the stoichiometry. C7H6O + 2 CH4O → C9H12O2 + H2O In a reaction, 10.0 g of benzaldehyde are mixed with 2.69 g of methanol. What is the theoretical yield of benzaldehyde dimethyl acetal in grams?

Draw the mechanism and the product(s)for the acid-catalyzed reaction of (S)-4-chloro 2-pentanone with 2 moles of methanol; indicate which is the hemiacetal and the acetal structures. Consider how would the mechanism and the product be different if the same ketone underwent acid hydrolysis in the absence of methanol? Also, consider the reversibility of the above mechanisms.

me by stating details about what happened, which group was the
protecting group, and how it lead to the final product being
formed.
In this experiment, you will perform a stereoselective reaction by protecting a 1,3-diol as an acetal. The classical acetalization reaction involves either a diol or multiple alcohols and a carbonyl species such as an alcohol or ketone. This process requires efficient removal of water from the reaction, which can be experimentally challenging....

How many products would you expect from the reaction of (S)-2-methylcyclohexanone with methyl magnesium bromide (include the stereoisomers)? Draw the stereoisomers of the product and specify the relationship between them. Following is a cyclic acetal formed from cyclohexanone. What are the reagents required for this reaction? Also write a stepwise mechanism for the formation of this acetal from cyclohexanone. Show how to synthesize the following compounds using a Wittig reaction.
