a) what is a ligroin
b)can you suggest an althernative solvent that might be used in this steps
Homework Answers
Contrary to its name, petroleum ether does not contain any ethers at all, rather it is a mix of nonpolar hydrocarbons.
Thus, solvents that could potentially be used as a replacement are any of the common hydrocarbon solvents, such as pentane or hexane.

seperation of acid neutral
Experiment 5: Separation of Acid-Neutral Mixture Post-Lab Questions 1. Draw and label the structures of the major and minor components of the acidic and neutral mixtures. 2. Although acetic acid - water may be used as a "solvent pair", why are dilute solutions of an inorganic acid/water (or, inorganic base/water) avoided in recrystallization attempts? (Hint: see Wade Ed: Sections 21-12, 21- 13. Consider functional-group possibilities.] 3. Using a flow diagram, show the separation of a mixture...

1. Polarimetry can be used to: (more than one answer may be correct) -measure the rotation of plane polarized light, but no further analysis can be carried out using the sample. -separate a pair of optical isomers. -find out which isomer of a chiral product you have made, by comparing the specific rotation to literature values for the same solvent, temperature, and wavelength. -determine the optical purity of the purified product from an enantioselective reaction. -determine the optical purity of...

1. a) Why does biphenyl have a higher Rf value than either benzophenone or triphenylmethanol? Explain based on the structures and their effect on mobility in the TLC process. b) Which compound, benzophenone or triphenylmethanol has a higher Rf value? Explain, based on their structures, how you can predict this. c) You developed your TLC using a 10% mixture of diethyl ether in petroleum ether. Petroleum ether is a mixture of non-polar alkanes, so this TLC solvent is composed of...
