Question

what type of intermolecular forces is/are present in hbr? * h——br: london dispersion forces only dipole - dipole forces only london dispersion forces and dipole - dipole forces dipole - dipole and hydrogen bonding dipole - dipole, hydrogen bonding, and london dispersion forces ionic ionic and london dispersion forces

Explanation:

1. London - Dispersion forces are present in all molecules as they result from temporary dipoles caused by the motion of electrons.
2. HBr is a polar molecule due to the electronegativity difference between H and Br. So, dipole - dipole forces are also present.
3. Hydrogen bonding occurs when H is bonded to a highly electronegative atom (N, O, or F), which is not the case in HBr. Also, HBr is a covalent compound, not ionic.

Answer:

C. London Dispersion forces and dipole - dipole forces
