Step 1: Recall the concept of polarity in chemistry.
Polarity refers to the separation of charges in a bond or a molecule. The degree of polarity depends on the electronegativity difference between the atoms forming the bond.
Step 2: Review the electronegativities of the atoms involved.
The electronegativity values (on the Pauling scale) for hydrogen (H), fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) are approximately 2.20, 4.0, 3.16, 2.96, and 2.66, respectively.
Final Answer
The ranking order of the degree of polarity for HF, HCl, HBr, and HI is HF > HCl > HBr > HI.
