Provide Explanation.
When the molecule is not symmetrical the base can abstract a hydrogen at either a carbon. Thus, a reaction can occur at two different regions of the molecule. Reaction 1 R-Br - A + HB PE 0 RC Question: Which alpha carbon's hydrogens are less sterically hindered and would be abstracted at a faster rate: Hydrogens on carbon a or b. a orb Question: Which enolate would form at a lower temperature - Kinetic control. A or B...

16. ROAD MAP: Compounds A, B, and Care constitutional isomers. Treatment of A or B with potassium tert-butoxide gives the same alkene D. If the base is changed to a less sterically hindered base such as sodium ethoxide, A and C give the same alkene E as the major product. Treatment of C (spectroscopic data given on next page) with potassium tert-butoxide gives yet another alkene F as a minor product. Compound B reacts...

Provide a brief explanation for the following experimental observations: a) The pKa value of H2SO4 is lower than the one of H2SO3. Estimate the expected pKa values in water. b) The gas phase proton affinity of benzophenone is larger than the one of acetone. c) 4-Dimethylaminopyridine, DMAP, is a stronger Brønsted base than pyridine. d) Anhydrous phosphoric acid, H3PO4, exhibits electrical conductivity. e) Dimethylsulfoxide, DMSO, binds to AlCl3 via the oxygen atom but to AgCl via the sulfur atom
