WebSelect all the statements that correctly explain why ketones are less reactive than aldehydes. The two alkyl groups of a ketone stabilize the partial charge on the carbonyl C, making it less reactive. An aldehyde is less sterically crowded, allowing nucleophilic attack to occur more easily. WebThis study guide summarizes the key points for reactivities of aldehydes and ketones and the main addition reactions with water, alcohols, amines, and cyanides. These together with protecting groups for aldehydes and ketones, the Wittig reaction and 1,2/1,4 additions to α, β -unsaturated compounds are covered with specific examples.

WebWhy are ketones less reactive than aldehydes? A. Ketones are more sterically hindered. B. Ketones are less electron deficient due to donation from the two alkyl groups. C. C. The statement is false; ketones are more reactive than aldehydes. D. Both A and B D If a compound is reduced, what is the result? A. Fewer C-H bonds WebDec 10, 2024 · Formaldehyde, acetaldehyde, and acetone are soluble in water. As the carbon chain increases in length, solubility in water decreases. The borderline of solubility occurs at about four carbon atoms per oxygen atom. All aldehydes and ketones are soluble in organic solvents and, in general, are less dense than water. WebSolution.
