Dat organic
Aldehyde + ketone
Question | Answer |
---|---|
aldehyde gen formula | R-C=O \H |
ketone gen formula | R-C=O \R |
in aldehyde the C=O occupies | C-1 |
cycloalkane+ aldehyde | cycloalkanecarbaldehyde |
in ketone if C=O is substituent attached to carboxylic acid | "oxo" prefix |
Synthesis of aldehyde using alcohol "oxidation" | primary alcohol with PCC/ na dicromate |
synthesis of ketone using alcohol | sec alcohol with PcC/na dicromate |
synthesis of aldehydes/ketone using alkene | ozone + alkene |
keto form | C=O |
enol form | C-OH |
C=O is polar therefore liable for | nucleophilic attack |
water + aldehyde or ketones | H added to O and OH added to C R-C-OH OH/\R |
alcohol + aldehyde or ketone | H added to O and RO added to C R-C-OH RO/\R (hemicetal(H) or hemiketal (R) |
acetal | 2OH added to aldehyde R-C-OR OR/\H |
ketal | 2 OH added to ketone R-C-OR OR/\R |
HCN + aldehyde/ ketone | H adds to O and CN to C R-C-OH CN/\R |
ammonia + aldehyde/ ketone | forms imine R-C=NH \R |
aldol | has both aldehyde and alcohol H-C=O \C-R-OH |
aldol + heat | loses OH and H from R to form double bond H-C=O \C=R |
wittig rxn | convert aldehydes and ketones to alkenes (C=O to C=C) ylide/ phosphorane + aldehyde or ketone |
ketones can be reduced to | alcohols |
aldehydes can be oxidized to ____ and reduced to ____ | carboxylic acids; alcohol |
aldehyde + KmnO4 CrO3 Ag2O or H2O2 | carboxylic acid |
ketone + LAh or NaBh4 | alcohol |
wolf kishner | aldehyde or ketone completely reduced to alkane H2NNH2 in base |
clemmensen | aldehyde or ketone reduced to alkane HgZn in HCL (acid) |
iodoform tests | methyl ketones |
