3)What is the major purpose of pyridine in nucleophile acyl
substitution reactions (for example, a reaction including an acid

i. What is the purpose of the cyclic acetal in the following reaction? ii. Draw the product formed if the original starting material was treated with 1. LiAlH4 & 2. H20 (i.e. what would happen if the 1st and 3rd reactions were not performed?)...

Why do aldehydes undergo nucleophilic addition reactions while acyl chlorides undergo nucleophilic acyl substitution reactions? Once the nucleophile adds to the aldehyde, the tetrahedral intermediate is too sterically hindered to eliminate one of the attached groups. Because an Sw2 substitution can best take place on the sphybridized carborwyl carbon of the acyl halide. Once the nucleophile adds to the aldehyde, neither H" nor Rºcan function as a leaving group. so a substitution cannot take place. The carbonyl carbon of the...

(7 points) Explain why esters are more reactive towards nucleophilic acyl substitution compared to amides. Your answer should be clear and concise. Writing more than necessary only increases the odds of writing an incorrect statement, which could result in points off. nucleophilic acyl substitution Nu R X R Nu - - - - - - - - - - O RO R NO Ester Amide

9) 9) Why do aldehydes undergo nucleophilic addition reactions, whereas esters undergo nucleophilic acyl substitution reactions? A) The carbonyl carbon of an ester is more electrophilic than that of an aldehyde. B) Once the nucleophile adds to an aldehyde, neither H- nor R-can be eliminated because they are strongly basic. C) Aldehydes are more sterically hindered than esters. D) The ester carbonyl carbon is sp3 hybridized while the aldehyde carbonyl carbon is sp2 hybridized. E) Once the nucleophile adds to...
