Is HCl a dipole dipole?
Chlorine has a higher electronegativity than hydrogen so will, thus, pull more electrons towards it.
This can allow for dipole-dipole interactions to occur.
Remember to check electronegativity values to see if a dipole would be created between two atoms. If two atoms have the same electronegativity value then no dipole will be creation, for example
As a side note: Do remember that the atom which pulls more electrons towards it will always have a
