| Question | Answer |
| Alkene + hydrogen --> alkane (also addition polymerisation) | Nickel catalyst 150 degrees C high pressure OR Platinum catalyst room temp and pressure |
| Primary alcohol -oxidation-> aldehyde -oxidation-> carboxylic acid | Acidified potassium dichromate |
| Secondary alcohol -oxidation-> ketone | Acidified potassium dichromate |
| Alcohol --> alkene + water (dehydration/ elimination) | 1- Alcohol vapour is passed over a hot catalyst of pumice stone or aluminium oxide 2- Reflux alcohol with excess concentrated sulfuric acid at 170 degrees C |
| Alkene + water --> alcohol (lab) | Cold concentrated sulfuric acid catalyst |
| Alkene + steam --> alcohol (industrial) | Solid phosphoric acid catalyst 300 degrees C 60 atm |
| Alcohol + HCl--> halogenoalkane | HCl and high heat |
| Nucleophilic substitution OH- + halogenoalkane --> alcohol + halide- | Warm aqueous sodium hydroxide |
