Which of the following correctly describes the direction of bond polarity in a molecule of HCl?
A
From Cl to H
B
No bond polarity exists
C
From H to Cl
D
Bond polarity is equal in both directions
Verified step by step guidance1
Understand that bond polarity arises due to the difference in electronegativity between two atoms in a bond.
Identify the electronegativities of hydrogen (H) and chlorine (Cl). Chlorine is more electronegative than hydrogen.
Recall that the bond polarity arrow points from the less electronegative atom to the more electronegative atom, indicating the direction of electron density shift.
Since Cl is more electronegative than H, the bond polarity arrow points from H to Cl, meaning electrons are pulled toward Cl.
Therefore, the correct description of bond polarity direction in HCl is from H to Cl.
