Give one chemical test to distinguish between the following pair of compounds : 1-propanol and 2-propanol asked Jan 12, 2019 in Chemistry by kajalk ( 78.6k points) alcohols phenols and ethers
What contains a hydroxyl group attached to a benzene ring? phenol. What is the function group in alcohols and phenols? OH. What is the product of oxidation of secondary alcohols? Ketones. What is the number of carbon atoms in 3-methyl 1-pentanol? 6. 1 in methyl and 5 in pentanol.
Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
Solution. (i) When propan-2-ol and 2-methyl-propan-2-ol are treated with copper at 573k, different products are formed. From the nature of the products we can distinguish them. (ii) Lucas test. When propan-2-ol and 2-methyl-propan-2-ol are treated with lucas reagent (conc. H Cl+ anhydrous ZnCl2) at room temperature, from the turbidity formation
In case of tertiary alcohols, instantaneous turbidity appears in the solution while in secondary alcohols turbidity appears after 4-5 minutes. 2-butanol is a secondary alcohol so turbidity will appear after 4-5 min while 2-methyl-2-propanol is a tertiary alcohol so immediate turbidity will appear and hence the two can be distinguished.
Obtain six test tubes and into separate test tubes add 5 drops of ethanol, 2-propanol, 2-methyl-2-propanol, cyclohexanol, 20% phenol, and the unknown solution 7. Obtain the 10% FeCl3 solution and at 5 drops to each solution 8. Stir each test tube and record your observations Choose Dark purple Choose Yes Phenol BINIU XIX - Choose Dark purple
