Exercise Predicting Types and Strengths of Attractions Between Particles: 

For each of the following substances, write the name for the type of particle that forms its basic structure and the name of the primary type of attraction between these particles. From each pair of substances, choose the one that you expect to have stronger interparticle attractions.

a. ethanol, C2H5OH  (in alcoholic beverages)

dimethyl ether, CH3OCH3  (refrigerant and solvent for propellant sprays)

b. manganese, Mn  (improves corrosion resistance and hardness when alloyed with other metals)

carbon tetrachloride, CCl4  (used for metal degreasing and to add chlorine atoms to organic compounds)

c. propane, C3H8  (fuel and aerosol propellant)

n-heptane, C7H16  (standard for octane rating)

d. acetone, CH3COCH3  (solvent for paints and varnishes)

lithium nitrate, LiNO3  (used to make ceramics and in rocket propellants)

e. antimony tribromide, SbBr3  (a molecular compound used as a mordant, which fixes dyes to textiles)

antimony trichloride, SbCl3  (a molecular compound used for fireproofing textiles)
