What reagents will separate, isolate, and purify 50% phenanthrene, 40% methyl 4-aminobenzoate, and 10% 1,4-dibromobenzene?

The reagents to chose from are: 1 M naoh, 6 M naoh, 1 M hcl, 6 M hcl, 1 M nahco3, saturated sodium chloride, diethyl ether, 95% ethanol, methanol, isopropyl alcohol, acetone, hexane, toluene, methylene chloride and anhydrous sodium sulfate.

95% ethyl alcohol is the best solvent for the solid compound you just mentioned above which in total will be equally amount to 100% it's one compound though mentioned in three different components this is a solid that yu have to purify finding which solvent is soluble ,next extracting the organic layer finally crystallizing it so it is in its purest form.... Toluene is to soluble and the compound you just mentioned will not crystallize after it has been dissolved with toluene making ethyl alcohol 95% the best aqueous solution.

To separate, isolate, and purify the components in the mixture (50% phenanthrene, 40% methyl 4-aminobenzoate, and 10% 1,4-dibromobenzene), you can use a combination of different reagents and techniques. Here's a step-by-step approach:

1. Initial Extraction:
- Start by extracting the mixture with a suitable organic solvent. In this case, diethyl ether or dichloromethane (methylene chloride) would be good choices.
- Add the organic solvent to the mixture and shake vigorously to ensure thorough mixing.
- Allow the layers to separate into an organic phase and an aqueous phase.
- Carefully separate the organic phase.

2. Separation of Phenanthrene:
- Since phenanthrene is nonpolar, it can be separated from the organic phase by using a polar solvent such as methanol or ethanol.
- Add either methanol or ethanol to the organic phase containing the phenanthrene.
- Shake gently to mix, then allow the layers to separate.
- Collect the upper layer (polar solvent with phenanthrene) and transfer it to a clean container.
- Evaporate the solvent using a rotary evaporator or by other means, leaving behind purified phenanthrene.

3. Separation of Methyl 4-Aminobenzoate:
- Methyl 4-aminobenzoate is relatively polar and can be separated using a basic solution.
- Add a 1 M NaOH solution to the remaining organic phase from step 2 and mix well.
- Allow the layers to separate, and this time, collect the lower layer (aqueous phase).
- Acidify the collected aqueous phase using a 1 M HCl solution.
- The resulting precipitate should contain the purified methyl 4-aminobenzoate.
- Filter the mixture, wash the precipitate with water, and allow it to dry to obtain the pure compound.

4. Separation of 1,4-Dibromobenzene:
- 1,4-Dibromobenzene can be separated from the remaining organic phase by selectively precipitating it.
- Add a saturated sodium chloride solution to the organic phase and mix well.
- Collect the lower layer (aqueous phase) and discard it.
- Add diethyl ether or another nonpolar organic solvent to the remaining liquid.
- Shake gently to dissolve the remaining compounds, then allow the layers to separate.
- Collect the upper layer (organic phase) and add anhydrous sodium sulfate to remove any remaining water.
- Filter the organic phase and evaporate the solvent to obtain purified 1,4-dibromobenzene.

Please note that this is a general outline, and additional purification steps (such as recrystallization or column chromatography) might be necessary depending on the desired purity level.
