Why does the O side of H2O point toward the Na+ ion?
We are asked why does the O side of H2O points toward the Na+ ion which exhibits ion-dipole forces.
Ion-dipole interaction – occurs between an ion and a polar covalent compound
The ion here is Na+ while H2O is the polar covalent compound as evidenced by the Lewis structure:
Step 1: Determine the central atom in the molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
Step 4: Determine the polarity and IMF of the molecule.
