H CH3 1. LDA 2. CHal НН H3C CN H3C CN Monocarbonyl compounds can be alkylated at the a position via the use of lithium disopropylamide, a strong, sterically hindered base Because only one carbonyl group is available to participate in resonance stabilization of the enolate, the a-hydrogens are less acidic than those of P-dicarbonyl compounds and so a stronger base is necessary to completely convert the compound to the enolate. The reaction occurs in a pola aprotic solvent such...

1. What type of intermolecular force is predominant in the following two compounds? H3C -C-CH3 H3C- CH-CH (3 points) 2. Hydrazine (NH2NH2), hydrogen peroxide (HooH), and water (H20) all have higher boiling points in comparison with other substances of comparable molecular weights. What structural property do these substances have in common, and how might that account for (4 points) their high boiling points? 3. The most significant factor which is responsible for the higher boiling point of ethanol C2H5OH, compared...
Sn(OH)2 is a sparingly soluble salt with very low molar solubility in pure water. Which change should increase the molar solubility of Sn(OH)2 O Add Sn(NO3)2 O Grind the Sn(OH)2 into a fine powder Add strong acid O Add more water O None of these O Add strong base
dilu SLUHY Udses, velduse ule ujuydte udbe vid Struny dulu is too weak to establish any meaningful equilibrium in solution. Figure 2: After Neutralization, F. Re-establishes an Equilibrium. Free Free Conclusions 1. The initial reaction between a weak acid and a strong base is not an equilibrium. Each mole of base deprotonates one mole of acid in an "irreversible" (very large K value) reaction. 2. Neutralization of a weak acid with strong base produces a conjugate base that will react...
