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. WebChemical Compounds Nucleophilic addition. Both aldehydes and ketones undergo many of these reactions, although aldehydes are usually much more reactive, for two reasons. First, it is easier for a nucleophile to approach the positive carbon atom of an aldehyde molecule, which always has one bond attached to the small hydrogen atom. highland park high school football scoreWebReactions of Aldehydes and Ketones Reactions of Aldehydes and Ketones Chemical Analysis Formulations Instrumental Analysis Pure Substances Sodium Hydroxide Test … highland park high school dallas tx

"WebAnd what we're going to do is drop the E and add "-AL" for aldehyde. So this would be "Butanal," right. So a four-carbon aldehyde is "butanal" with an "-AL"ending like that. Let's go ahead and look at some more examples. So once again we're going to number to give our carbonyl carbon the lowest number possible. " - Reactivity of aldehyde and ketone
