Question

Identify the principle intermolecular attractive forces exhibited by each of

the following compounds:

a. CH₃CH₂OH

b. CH₃F

c. H2S

d. I₂

Answer 1

a) CH3CH2OH

Hydrogen bond

Hydrogen bond exists in compounds in which hydrogen is attached to higher electronegative atoms such as Nitrogen, Oxygen and Flourine.

b) CH3F

Dipole - dipole forces

CH3F is polar compound but having no possiblity for hydrogen bond , so the principle inter molecular atractice forces is dipole - dipole forces

c) H2S

Dipole - dipole forces

H2S is polar compound but having no possiblity for hydrogen bonding , so the principle intermolecular forces is dipole - dipole forces

d) I2

London dispersion forces

I2 is nonpolar compound , so the principle intermolecular forces is London dispersion forces.
