Identify the major intermolecular forces between each of the following atoms or molecules:

Question

a. He
b. HBr
c. SnH4
d. CH3¬CH2¬CH2¬OH

I think b and c are hydrogen bonds. D is dipole-dipole attractions?

Answer 1

I don't think any of your answers are correct. See my answer to the same question above after reading the reference in Wikipedia.
SnH4 is a symmetrical molecule (like CH4). Dispersion forces is the obvious answer here. Alcohols, such as d, are H bonding.
He is due to dispersion forces. Aren't the bonds in HBr ionic? Read that link to wikipedia.
