Question

Ming has two unknown substances. One is nonpolar, and the other is polar.

Which process would most likely help Ming identify which substance is polar and which is nonpolar?
Test the boiling points. The polar substance should have a lower boiling point because of its dipole-dipole forces.
Test for an odor. The nonpolar substance should have a higher volatility and stronger odor because of its London dispersion forces.
Test the boiling points. The nonpolar substance should have a higher boiling point because of its hydrogen bonds.
Test for an odor. The polar substance should have a higher volatility and weaker odor because of its dipole-dipole forces.

Answer 1

Test for an odor. The nonpolar substance should have a higher volatility and stronger odor because of its London dispersion forces.

Step-by-step explanation:

To help Ming identify the non-polar compound, assuming the non-polar compound will have an odor test for it and most importantly, the non-polar substance should have a higher volatility due to its London dispersion forces.

• London dispersion forces are weak attractions found between non-polar molecules and noble gases.
• They account for the reason why compounds as such are volatile
