4. The carbonyl carbon of an aldehyde or a ketone is appreciably positive and is therefore, susceptible to nucleophilic attack. Tell which member of each pair of compounds will be more reactive towards a nucleophile. Explain your choice. a. p-ethoxy acetophenone or p-cyanoacetophenone b. benzaldehyde or methyl phenyl ketone c. 3-methyl butanone or 2-methylpentan-3-one d. 3-chloropentanal or 2-bromo-3-chloropentanal e. butanedione or pentane-2,4-dione

Why is the bromination (EAS) of phenyl ester slower than phenol?
1. Put these three common types of carbonyl compound in order of decreasing reactivity ester amide acid chloride 2. For the least reactive, show the interconversion to its other resonance form: How does this electron delocalisation make it stable? 3. For the most reactive, draw the mechanism of its undergoing hydrolysis (reaction with H2O): Why makes this type of carbonyl so reactive to nucleophiles?

Can you help find the best reagent for this problem?
Which side product could be expected in this reaction if the product of the first addition, benzalacetone, reacts with acetone instead of the benzaldehyde? please show the structure of the side product and the mechanistic step(s) showing how it is formed. thanks in advance
Write structures for the carbonyl electrophile and enolate nucleophile that react to give the aldol below. You do not have to consider stereochemistry. Draw the enolate nucleophile in its carbanion form. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate multiple reactants using the + sign from the drop-down menu.
In this reaction, why doesn't the NH2 group trigger an elimination instead of the substitution reaction seen in the picture? Why can't the -NH2 remove a proton, causing the C-H bond to collapse and form a triple bond (benzyne), and the Cl is removed as a leaving group?
How does changing the halide from (CH3)3CBr to CH3CH2CH2Br affect the rate of an E1 reaction?
