Chapter 9: Q. 9.85 (page 317)

Why does iodine dissolve in hexane, but not in water? (9.1)

Short Answer

Expert verified

Although iodine is a non-polar molecule. As the result it will absorb in hexane but not in water.

Step by step solution

01

Given  information

Organic solvents can easily diffuse all non-polar compounds, although all polar molecules can absorb polar molecules. Iodine should dissolve the most in nonpolar solvents because it is a nonpolar chemical. Iodine is best dissolved in diethyl ether.

02

Explanation.

Since iodine is a non-polar ion, it will melt in a non-polar solvent like hexane. While water is a polar solvent, lodine does not react in it.
