Dipole dipole forces are an important factor to consider in determining whether or not a substance will dissolve in water (a molecule which has a dipole). Which of the following compounds would you expect to be the most soluble in water?

Question

Quizplus · Accepted Answer

Out of the given compounds, only compound B (NH₃) contains a polar covalent bond with a significant dipole moment. This is due to the electronegativity difference between nitrogen and hydrogen atoms in the molecule. Water, being polar, will be able to interact with the dipole of the nitrogen-hydrogen bond in compound B through dipole-dipole interactions, increasing the solubility of the compound in water. Therefore, compound B is the most soluble in water out of the given options.
