List the types of intermolecular forces that exist between molecules (or basic units) in each of the following species: (a) benzene (C6H6), (b) CH3Cl,

CPF3, (d) NaCl, (e) CS2.

Verified Answer :

Benzene (C6H6) = nonpolar molecules . Dispersion forces are present only.
Chloroform (CH3Cl)= polar molecules . Dispersion and dipole-dipole forces are
present.
Phosphorus trifluoride (PF3)
molecules are polar. Dispersion and dipole-dipole forces are
present.
Sodium chloride (NaCl) = ionic compound. Ion-ion and dispersion forces are present.
Carbon disulfide (CS2) = nonpolar molecules . Dispersion forces are present only.

Answer:

Answer has been given below

Explanation:

  • Every molecules contain electrons. So, London dispersion force exists in all molecules.
  • For polar aprotic molecules, additional dipole-dipole force exists between molecules.
  • For ionic compounds, additional ionic interaction force exist between ions.
  • For non polar molecules, only London dispersion force exists between molecules.
  • Benzene is a non-polar molecule. So London dispersion force exists between benzene molecules.
  • \(CH_{3}Cl\) is a polar molecule. So, dipole-dipole force and London dispersion force exists between \(CH_{3}Cl\) molecules.
  • \(PF_{3}\) is a polar molecule. So, dipole-dipole force and London dispersion force exists between \(PF_{3}\) molecules.
  • NaCl is an ionic compound. So London dispersion force and ionic interaction force exists between NaCl molecules.
  • \(CS_{2}\) is a nonpolar molecule. So, London dispersion force exists between \(CS_{2}\) molecules.
