$hobr$
$co_2$
$ccl_4$
$nh_3f$ (n is central)

Explanation:

Step1: Determine Lewis structure of PCl₃

P has 5 valence - electrons and Cl has 7. P is central atom. P forms 3 single bonds with 3 Cl atoms and has 1 lone - pair.

Step2: Check polarity of PCl₃

The molecule has a trigonal - pyramidal shape due to the lone - pair on P. The bond dipoles do not cancel out, so it is polar (Y).

Step3: Identify IMFs in PCl₃

It has dipole - dipole forces and London dispersion forces.

Step4: Determine Lewis structure of HOBr

H has 1 valence - electron, O has 6, and Br has 7. O is central atom. O forms single bonds with H and Br and has 2 lone - pairs.

Step5: Check polarity of HOBr

The molecule is polar (Y) due to the electronegativity difference and non - symmetric shape.

Step6: Identify IMFs in HOBr

It has hydrogen bonding (due to H attached to O), dipole - dipole forces, and London dispersion forces.

Step7: Determine Lewis structure of CO₂

C has 4 valence - electrons and O has 6. C forms double bonds with 2 O atoms.

Step8: Check polarity of CO₂

The molecule is linear and the bond dipoles cancel out, so it is non - polar (N).

Step9: Identify IMFs in CO₂

It has only London dispersion forces.

Step10: Determine Lewis structure of CCl₄

C has 4 valence - electrons and Cl has 7. C forms 4 single bonds with 4 Cl atoms.

Step11: Check polarity of CCl₄

The molecule is tetrahedral and the bond dipoles cancel out, so it is non - polar (N).

Step12: Identify IMFs in CCl₄

It has only London dispersion forces.

Step13: Determine Lewis structure of NH₃F (N is central)

N has 5 valence - electrons, H has 1, and F has 7. N forms 3 single bonds with H atoms and 1 single bond with F and has 1 lone - pair.

Step14: Check polarity of NH₃F

The molecule is polar (Y) due to the electronegativity difference and non - symmetric shape.

Step15: Identify IMFs in NH₃F

It has hydrogen bonding (due to H attached to N), dipole - dipole forces, and London dispersion forces.
