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...

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...

luction Nucleophilic substitution is a tremendously useful and important reaction in organic chemistry. No s it used extensively in organic synthesis, but some biochemical processes also proceed via nucleophili Litution mechanisms. Often, nucleophilic substitution is one of the first organic reactions covered and it efore very important to understand it thoroughly. This experiment investigates the relative nucleophilicity of chloride and bromide ions. Also of interes ow varying the degree of substitution at the electrophilic center affects the reaction mechanism. The...

Nucleophilic Acyl Substitution Nucleophilic Acyl Substitution is a major reaction for acids and acid derivatives. This is the reaction that converts one derivative into another. The substitution can occur in basic or acidic condition, depending on a derivative. Nucleophilic Acyl Substitution in Basic Conditions-general mechanism NUCLEOPHILIC ATTACK LOSS OF A LEAVING GROUP Nue Nuc Nuc Note: in cases when the nucleophile is neutral (H20, ROH,RNHzl, the mechanism includes one more step: deprotonation of an already attached Nuc: group by another...

V. Pyridine ( ) is often used as a catalyst for the nucleophilic acyl substitution reaction between an acyl chloride and an alcohol. Please explain why the use of pyridine can accelerate such a reaction: (hint: the basicity of pyridine is about 10^6 times stronger than an alcohol.)
