What are the various solvents for the following solutes?

a. wax b. plant pigment c. glucose d. coaltar e. fat

To identify the solvents for different solutes, we need to consider the solubility of each solute in different solvents. The solubility is determined by the intermolecular interactions between the solute and solvent molecules.

a. Wax: Wax is generally insoluble in polar solvents, such as water, but is soluble in nonpolar solvents. One common nonpolar solvent for wax is hydrocarbon-based solvents like hexane or toluene.

b. Plant pigment: Plant pigments, such as chlorophyll, are generally soluble in polar solvents. Common polar solvents for plant pigments include ethanol, methanol, and acetone.

c. Glucose: Glucose is highly soluble in both polar and protic solvents. Water is the most common solvent for glucose due to its polarity and ability to form hydrogen bonds with glucose molecules.

d. Coaltar: Coaltar is a complex mixture of organic compounds. It is typically insoluble in both polar and nonpolar solvents. However, coaltar can be partially soluble in certain organic solvents like benzene or xylene.

e. Fat: Fats are nonpolar substances and are generally insoluble in polar solvents like water. Fat can dissolve in nonpolar solvents such as ether, chloroform, or hexane.

It's worth noting that the solubility of a solute can vary depending on factors such as temperature and concentration. Additionally, the solvents mentioned above are just examples and there can be other solvents suitable for a particular solute. Conducting solubility tests and referring to literature sources can provide more specific information on solvent selection for various solutes.
