Question

do you agree that HCL is the beast choice for a substance that has both dipersion forces and dipole-dipole forces ?
The choices I have are :
Br2
HCl
H2
CO2
BCl3

HCL is the most sensible answer.
Do you reckon so too?
thanks andy

I agree. Have you studied shape? Br2 is linear (no dipole), H2 is linear (no dipole), CO2 is linear (no dipole) and BCl3 is trigonal planar (no dipole). All of them have dispersion forces, HCl is the only with that is polar (therefore, the only one that could have a dipole).

Wow great!!! thanks very muchyou are right when you look at the shape in the book...it actually becomes obvious Andy
