Which of the following are true for HBr?

Question

a)the strongest intermolecular forces are dipole-dipole

b)in an individual molecule, the bonds between H and Br are ion-dipole

c) this is a covalent compound

d) the intermolecular forces are relatively weak

Note: hydrogen bonds are a specific type of dipole-diplole interactions. Thus in the above question, dipole-dipole forces include hydrogen bonds. Please help, thank you.

Answer 1

A and C

The bonding between H and Br is polar-covalent. The molecule itself is a dipole with oppositely charged ends. Therefore the intermolecular forces are dipole-dipole.
