| Question | Answer |
| Alcohol to Aldehyde | Pyridinium Chlorochromate C5H5NH+CrO3Cl- |
| Cycloalkane to Cycloketone | Chromic Oxide CrO3 |
| Fluorotoluene to Fluorobenzaldehyde | 1. Etard reaction (CrO2O3 ->Chromium complex-> Aldehyde) 2. CrO3 + acetic anhydride -> benzylidenen diacetate -> Aldehyde |
| Ethanenitrile to Ethanal | 1. Stephen reaction (SnCl2 + HCl -> Imine -> Aldehyde) 2. Reduction with DIBAL -H -> Hydrolysis |
| Allyl alcohol to Propenal | PCC |
| But-2-ene to Ethanal | Ozonolysis / H2O - Zn dust |
| Order of boiling points | Hydrocarbon < Ether < Aldehyde < Ketone < Alcohol 1. Hydrocarbon - van der Waal's forces 2. Aldehyde > Ether - More polar 3. Aldehyde, ketone < Alcohol - only weak dipole-dipole interactions as opposed to hydrogen bonding |
