what is the suffix for aldehydes
-al
what is the suffix for ketones
-one
what is formaldehyde
one C aldehyde
what is acetaldehyde
aldehyde with 2C
what is acetone
3 C
how can aldehydes be formed from primary alcohols
strong oxidation agent such as pyridinium chlorochromate (PCC)
how can aldehydes be formed via ozonolysis
cleave aldehyde if either carbon is attached to a H atom
what is required for aldehyde formation from ozonolysis
O3 with DMS
how can ketones be formed from secondary alcohols
oxidising agent
Na2Cr2O7 with H2SO4 and H2O
how can ketones be formed from ozonolysis
tetrasubstituted alkenes cleaved to form ketones
what is friedel crafts acylation
aromatic rings react with acyl halide in presence of lewis acid to produce aryl ketone
aldehydes with oxidize easier/harder than ketones
easier
will aldehydes or ketones undergo nucleophilic addition easier
aldyhydes
how do aldehydes form hemiacetals
dissolved in primary alcohol
