Identify the priincipal intermolecular forces in each of the following substances: HF, C4H8, NCl3, Br2, HI

Identify the priincipal intermolecular forces in each of the following substances: HF, C₄H₈, NCl_3, Br₂, HI

Expert Solution

HF : This molecule has dipole-dipole, hydrogen bonding, London dispersion forces as intermolecular forces. But hydrogen bonding forces are principal intermolecular forces as it is more strong than remaining intermolecular forces.

Answer: hydrogen bonding forces are principal intermolecular forces.

C4H8 : It is non-polar molecule so it has only London dispersion (van der Wall's) forces as intermolecular forces.

Answer: London dispersion (van der Wall's) forces are principal intermolecular forces.

NCl3 : This molecule has dipole-dipole, London dispersion forces as intermolecular forces. But dipole-dipole forces are principal intermolecular forces as it is more strong than remaining intermolecular forces.

Answer: dipole-dipole attraction forces are principal intermolecular forces.

Br2 : It is non-polar molecule so it has only London dispersion (van der Wall's) forces as intermolecular forces.

Answer: London dispersion (van der Wall's) forces are principal intermolecular forces.

HI : This molecule has dipole-dipole, London dispersion forces as intermolecular forces. But dipole-dipole forces are principal intermolecular forces as it is more strong than remaining intermolecular forces.

Answer: dipole-dipole attraction forces are principal intermolecular forces.
