Chapter 6 Flashcards
aldehydes
end in -al or oxo-
common aldehydes
formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, valeraldehyde
if on ring= carbaldehyde
ketones
-one or keto/oxo-
2-propanone
dimethyl ketone or acetone
2-butanone
ethyl methyl ketone
carbonyl functions
dipoles can increase intermolecular
can act as electrophiles (aldehydes are more reactive due to sterics)
can be REDOX
nucleophilic addition
C=O is polarized which makes it a good electrophile
if theres a good LG the carbonyl reforms, if there is not a good LG it will form a hydroxyl
product will have a nucleophile and OH
hydration of aldehydes and ketones
form geminal diols (2OH)
water has nucleophile on O
SN1
catalyzed by acid
loose water, and second equiv of alcohol reacts with carbocation
form acetal or ketal
Imine
good nu, nitrogen double bonded to C
to form, ammonia adds to Carbon and water is lost
enamine
tautomer of imine
double bond and nitrogen
cyanohydrin
Nu, triple bond with N
acidic
reducing agents
LiALH4 and NaBH4
