Predict the relative order of reactivity of the indicated
carbonyl compounds in reactions with
nucleophiles (1 = most reactive carbonyl electrophile). Use
all three logic arguments of organic chemistry (resonance,
inductive and steric). Show structures, lone pairs and
arrow-pushing conventions in your answer to provide an explanation
for your order of reactivity. Write the expected product in a
reaction with lithium aluminium deuteride, LiAlD4, followed by
workup (no mechanisms)

5. Resonance provides the basis for a large portion of organic chemistry and helps us identify sites of high and low electron density. We will see that the electron source (nucleophile) is attracted to the site of electron sinks or deficiency (electrophile). For the following, draw the curved arrow that shows the movement of electrons that takes you from one resonance structure to the other. Remember to always start your arrow at the source of electrons (r-bond or lone pair)....

2) Rank the nucleophiles given below based on high, mediocre,
and low nucleophilicity and reason why based on their structures.
HO-CH3, H2N-CH3, KO-CH3, KO-C(CH3)3
Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by...

draw organic structures for the following
Organic acids and bases, to the extent that they are relatively non-polar, may be only sparingly soluble in polar water. Benzoic acid, as a predominantly non-polar molecule, is expected to be more soluble in non- polar ether than in water. Benzoic acid, however, can be chemically manipulated to benzoate ion, thus greatly increasing its solubility in water. Since it is an acid, it will react with a base like NAOH (aq) according to the...

1. Draw all the significant resonance forms for the following structures, and indicate which are major and which are minor, or if you have two equally important forms, say so. The number of new forms you need to draw is shown in parentheses below the arrow. (a) N co 4. In each of the following reactions, indicate which structure is the nucleophile and which is the electrophile. Also draw the products (use the electron pair arrows to guide you). (a)...
