•Aldehydes are generally more reactive towards nucleophiles than ketones: 1 Steric effects-aldehydes are less sterically hindered 2 Electronic effects-aldehyde has a largerd+on the carbonyl carbon: •Some nucleophiles require acidic conditions others require basic conditions •Example: the Grignard reaction = basic conditions

The Boiling Points of Aldehydes and Ketones Since there is no hydrogen on the carbonyl oxygen aldehydes and ketones do not form hydrogen bonds with themselves Aldehydes and ketones therefore have boiling points that are in between those of alcohols and hydrocarbons of the same molecular weight:

14 4 Reduction of Aldehydes and Ketones In reduction reactions of aldehydes and ketones we add hydrogen across the double bond That is a hydrogen atom will be added to each atom of the double bond converting the aldehyde or ketone into an alcohol We can add this hydrogen in one of two different ways The first is to
Why is an aldehyde more reactive than a ketone?
- Aldehydes are usually more reactive toward nucleophilic substitutions than ketones because of both steric and electronic effects. In aldehydes, the relatively small hydrogen atom is attached to one side of the carbonyl group, while a larger R group is affixed to the other side.
How can we differentiate aldehyde and ketone?
- length. Aromatic ketones are less reactive than aliphatic ketones. Aldehydes are much more reactive than ketones and their tendency to undergo the bisulfite addition is particularly strong. The formation of acetals and ketals can be suppressed by replacing methanol in the titrating agent with another solvent, typically pyridine or 2 ...
Which is more stable, an aldehyde or a ketone?
- Ketones are more stable than aldehydes. That is, aldehydes are typically much more susceptible to reactions than ketones are. Reasons for this are two-fold. Aldehydes, of course, have to have at least one hydrogen on one side of the carbonyl.
What is the reaction between alcohol and aldehyde?
- The alcohols are converted to aldehydes and ketones by the process of oxidation. This is one of the most important reactions in the field of organic chemistry. Oxidizing alcohols to aldehydes and ketones are one of the vital reactions in the field of synthetic organic chemistry.
