ALDEHYDES & KETONES Flashcards
Aside from Aldehydes & Ketones, what are the other carbonyl containing compounds?

Have at least 1 hydrogen atom attached to the carbonyl carbon.
Aldehydes
Have 2 carbon groups attached to the carbonyl carbon.
Ketones
C=O is called
carbonyl carbon
C=O with R group is called
Acyl group
C=O with Hydrogen is called
Formyl group
Aldehyde group is synonymous with?
Formyl group
Acyl group found on Aldehydes/Ketones is?
Bonded to a hydrogen (aldehyde) or another carbon (ketone).
AND
it CAN’T stabilize negative charge
AND
it CAN’T act as a leaving group in a nucleophilic substitution reaction
Acyl group found on Carboxylic acid is?
Bonded to an atom (can be Oxygen, Halogen, Sulfur, Nitrogen).
AND
it CAN stabilize negative charge
AND
it CAN act as a leaving group in a nucleophilic substitution reaction
Bonded to a hydrogen (aldehyde) or another carbon (ketone).

In nomenclature, carbon 1 would be the carbon with?
Carbonyl carbon
what suffix is added if the -CHO is attached to a cycloalkane
-carbaldehyde
what suffic is added if the -CHO is attached to a benzene ring
-benzenecarbaldehyde
Formaldehyde systematic name
Methanal
Acetaldehyde systematic name
Ethanal
Acrolein systematic name
Propenal
Crotonaldehyde systematic name
2-Butenal
Benzadehyde systematic name
Benzenecarbaldehyde
Propionaldehyde IUPAC name
Propanal
When is the prefix “oxo” used?
When ketone and aldehyde are NOT the functional groups; they become the substituent.
What functional group is higher than ketone and aldehyde?
Carboxylic acid and acid anhydride
Boiling point of Aldehydes & Ketones description?
Intermediate between alcohols and alkanes
Physical properties of aldehydes & ketones are due to the presence of?
Presence of carbonyl carbon (C=O)
carbonyl carbon (C=O) is polar or nonpolar?
Polar functional group
The boiling point increases with an increase in the size of the molecule so the chemical properties of Aldehydes & Ketones are due to the presence of a POLAR FUNCTIONAL GROUP or the CARBONYL CARBON.
Smaller compounds are soluble in water because?
They are Hydrogen bond acceptors.
The simplest aldehyde, is manufactured on a very large scale by the oxidation of methanol.
Formaldehyde
37% aqueous solution of Formaldehyde?
Formalin
It is a preservative and disinfectant; mostly used in the manufacture of plastics, building insulations, particle board and plywoods.
Formalin
It is a cold sterilant that is effective to kill microorganisms spores, resistant viruses used in proper concentration and even adequate contact time.
Formaldehyde
About half of acetaldehyde is produced anually to oxidize to?
Acetic acid
Manufactured mainly by the oxidation of ethylene over a palladium-copper catalyst.
Acetaldehyde
If ½ of acetaldehyde is used to oxidize acetic acid, the other ½ is used for?
Production of 1-butanol & other commercial chemicals.
