ALDEHYDES AND KETONES 5 1 Introduction H Aldehydes have a -C=O functional group An aldehyde requires that at least one of the bonds on the C=O group is a hydrogen atom When the carbonyl group (C=O) has two C atoms bonded to it is classified as a ketone 5 2 Naming Aldehydes and Ketones

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.
