In each of the given compounds, determine the kind of intermolecular forces existing between their molecules. Concept introduction: The attractive forces existing between molecules are said to be intermolecular forces. These forces are the result of mainly three types of interactions: (a) Dipole–dipole interactions (b) Dipole–induced dipole interactions (c) Induced dipole–induced dipole interactions There are four types of intermolecular forces: (a) Dispersion forces: These are the intermolecular forces present in all the molecules and atoms by virtue of the electrons present in them. (b) Dipole–dipole interactions: These are the forces that exist in all polar molecules. They have permanent dipole in which positive end of one permanent dipole is attracted to the negative end of other. (c) Hydrogen bonding: These forces exist in those molecules having hydrogen atoms bonded directly to the electronegative elements like fluorine, oxygen, or nitrogen. (d) Ion–dipole forces: Such types of forces exist between the ionic compound molecules.

Interpretation Introduction

Interpretation:

In each of the given compounds, determine the kind of intermolecular forces existing between their molecules.

Concept introduction:

The attractive forces existing between molecules are said to be intermolecular forces. These forces are the result of mainly three types of interactions:

(a) Dipole–dipole interactions

(b) Dipole–induced dipole interactions

(c) Induced dipole–induced dipole interactions

There are four types of intermolecular forces:

(a) Dispersion forces: These are the intermolecular forces present in all the molecules and atoms by virtue of the electrons present in them.

(b) Dipole–dipole interactions: These are the forces that exist in all polar molecules. They have permanent dipole in which positive end of one permanent dipole is attracted to the negative end of other.

(c) Hydrogen bonding: These forces exist in those molecules having hydrogen atoms bonded directly to the electronegative elements like fluorine, oxygen, or nitrogen.

(d) Ion–dipole forces: Such types of forces exist between the ionic compound molecules.

Hydrogen bonding in water plays a key role in its physical properties. Assume that the energy required to break a hydrogen bond is approximately 8 kJ/mol. Consider a simplified two-state model where a "formed" hydrogen bond is in the ground state and a "broken" bond is in the excited state. Using this model: • Calculate the fraction of broken hydrogen bonds at T = 300 K, and also at T = 273 K and T = 373 K. • At what temperature would approximately 50% of the hydrogen bonds be broken? • What does your result imply about the accuracy or limitations of the two-state model in describing hydrogen bonding in water? Finally, applying your understanding: • Would you expect it to be easier or harder to vaporize water at higher temperatures? Why? If you were to hang wet laundry outside, would it dry more quickly on a warm summer day or on a cold winter day, assuming humidity is constant?
