Question

4)Which of the following best explains the forces acting upon polar molecules?
a)They have ionic bonds which are acted upon by strong dipole forces.
b)They have high electronegativity values which account for strong London dispersion forces.
c)They have small atomic radii which make for greater forces of attraction.
d)They have partial charges and are bound together by dipole-dipole intermolecular forces.

Answer 1

Do you know what polar molecules are?

Answer 2

Not really lol

Answer 3

The answer is d)They have partial charges and are bound together by dipole-dipole intermolecular forces.

Answer 4

Oh thank you so much, just on more question

Answer 5

5) What type of bonding, molecular geometry (shape), and intermolecular forces for HF and HBr. Which substance would experience a stronger attraction between its molecules, and why?

Answer 6

Take water for example- it's polar, because it contains an oxygen atom highly electronegative, and hydrogen atoms weakly electronegative. Non metals are usually very electrogenative. This is what creates slight charges.

Answer 7

Thanks

Answer 8

5.What type of bonding, molecular geometry (shape), and intermolecular forces for HF and HBr.

>What type of shape can you get from joining 2 dots?

Which substance would experience a stronger attraction between its molecules, and why?

>The one with the greater separation of charge, i.e. dipole moment.

watch that video, it explains this
