解析 The OH is more acidic(pKa≈17)than the C α to the ketone(pKa≈20). Because the by−product of the reaction is H2O,there is no need to break the O−H bond to get to product,but the C−H bond α to the ketone must be broken....
Which pH value is the most acidic? A)5 B)7 C)12 D)2 Acids and Bases: Acidic and basic solutions have varying pH and so is a neutral solution. A solution is said to be neutral if it has a pH value equal to 7. At neutrality, the acidic and basic components are equal. But when...
