Question

3. Circle the intermolecular force(s) that is/are present in each of the following species. [Hint: there may be more than one correct answer.] (a) HCI (b) NH (hydrogen bonding, dipole-dipole interactions, dispersion forces) (c) CCl4 (hydrogen bonding, dipole-dipole interactions, dispersion forces) (d) He (e CH:C (hydrogen bonding, dipole-dipole interactions, dispersion forces) hydrogen bonding, dipole-dipole interactions, dispersion forces) (hydrogen bonding, dipole-dipole interactions, dispersion forces)

Explanation / Answer

1) in HCl hydrogen bonding is the intermolecular force present due to electronegativity difference of hydrogen and chlorine

2) in NH3 also hydrogen bonding is present

3) in CCL4 ,dispersion forces

4) He ,dispersion forces are present

5) CH3cl have dipole dipole interaction
