Question

2. What property of an atom defines the atom’s ability to attract electrons?

3. Is it possible for a molecule to have polar bonds, but still be nonpolar as an overall molecule?

4. Do solid ionic compounds conduct electricity?

5. Which type of compounds (molecular or ionic) generally produce electrolytes when dissolved in water?

6. Is it possible for a nonpolar molecule to become temporarily polar?

7. One of which three atoms are always found bonded to hydrogen in a molecule that has hydrogen bonding as

one of its intermolecular forces?

8. What property makes those three atoms so special/important as to be able to create the situation where

hydrogen bonding is possible?

9. What substance is the most commonly used example of hydrogen bonding?

10. What is the approximate energy associated with a hydrogen bond?

11. Which is the most order state of matter?

12. Which is the most disordered state of matter?

13. Who discovered the compressibility of gases in 1661?

14. What two pressures are equal when a liquid boils?

15. The normal boiling point is a reflection of the molecular weight of the compound and what other property?

16. Which forces of attraction must be greater in order for a substance to dissolve, solvent-solvent or solventsolute?

17. The general rule for solubility is that “__________ dissolves __________.”

18. Give the name of the reverse of melting.

2. What property of an atom defines the atom’s ability to attract electrons?

Electronegativity

3. Is it possible for a molecule to have polar bonds, but still be nonpolar as an overall molecule?

Yes, it is possoble, if they both cancel each other, for example CO2 molecule has 2 polar bonds, but overall is nonpolar

4. Do solid ionic compounds conduct electricity?

NO, they do not have delocalized electrons, then they will only conduce electricity only in aquous solution

5. Which type of compounds (molecular or ionic) generally produce electrolytes when dissolved in water?

ionic, since molecular are not likely to dissocaite at 100%
