Question

The forces that account for HF being a liquid while H2 and F2 are gases are known as:

A:dispersion forces
B:hydrogen bonding forces
C;dipole-dipole forces

Answer 1

hydrogen and fluorine gases are held together by weak dispersion force alone. not much energy needed to separate molecules, so they are gases. Hydrogen fluoride has strong hydrogen bonds, takes much more energy to separate these molecules, so at room temperature, HF is a liquid.

Answer 2

SO ITS B?

Answer 3

no, it c

Answer 4

look the "dipole-dipole forces" in HF are extremely strong, which forces the molecules in the H2 and F2 to bond strongly together. Therefore, HF exists as a liquid while the component elements are naturally found as gasses.
