Other questions in this quiz
2. How would you get an alicyclic amine?
- react nitrobenzene with nitrous acid below 10 degrees temp
- react nitrobenzene with HCl and tin under reflux
- react a halogenalkane with HCl and tin under reflux
- react a halogenalkane with aqueous ethanolic ammonia
3. How would you carry out a test to distinguish a carboxylic acid from a ketone?
- React with 2,4-DNPH, orange precipitate = aldehyde/ketone
- Add solid carbonate - fizzing as CO2 given off = aldehyde/ketone
- Oxidise with K2Cr2O7/H2SO4 - colour change = carboxylic acid
- Heat gently with tollens reagent, silver mirror = carboxylic acid
4. What observations would you record reacting potassium dichromate with a primary alcohol?
- Oxidising agent changes colour from orange to blue
- Oxidising agent changes colour from orange to green
- White precipitate formed
- Oxidising agent changes colour from yellow to orange
5. What are the reaction conditions and reagents for acid esterification reactions?
- RTP
- concentrated H2SO4, heat under reflux
- concentrated HCl and tin
- concentrated HCl, heat gently
