Question

which type of bond will most likely be found in hbr given that the electronegativity of hydrogen is 2.20 and the electronegativity of bromine is 2.96?
○ an ionic bond
○ a metallic bond
○ a polar covalent bond
○ a nonpolar covalent bond

Explanation:

Step1: Calculate electronegativity difference

$\Delta EN = 2.96 - 2.20 = 0.76$

Step2: Classify bond by $\Delta EN$

Polar covalent bonds have $\Delta EN$ between 0.4 and 1.7. Since $0.76$ falls in this range, the bond is polar covalent.

Answer:

a polar covalent bond
