The greater the different in electronegativity between bonded atoms, the?
A
lower the polarity of the bond
B
higher the polarity of the bond
C
weaker the bond
D
higher the possibility of the substance formed being a molecule
Verified Correct Answer: B.
Chemical Principles & Mechanism
Bond polarity and ionic character increase with an increasing difference in electronegativity.
The electronegativity (χ) of an element is the relative ability of an atom to attract electrons to itself in a chemical compound and increases diagonally from the lower left of the periodic table to the upper right.
