Step 1
Relative position of bonding electrons
Answer
In hydrogen chloride (HCl), the bonding electrons are shared between hydrogen and chlorine. Since chlorine is more electronegative than hydrogen, it will attract the bonding electrons more strongly. Therefore, the bonding electrons are positioned closer to chlorine.
Step 2
Dipole notation
Answer
The dipole notation reflects this arrangement by indicating a partial positive charge (δ+) on hydrogen and a partial negative charge (δ−) on chlorine. The correct notation shows the direction of the dipole moment, pointing towards the more electronegative atom (chlorine). Thus, the dipole notation will be:
H δ+ — Cl δ−.
