As the Difference in the Electronegativity Between Atoms Forming a Chemical

Question

As the difference in the electronegativity between atoms forming a chemical bond increases, the:
A) less polar the molecule.
B) more polar the molecule.
C) more stable the molecule.
D) more symmetrical the molecule.

Accepted Answer

As the difference in electronegativity between two atoms in a chemical bond increases, the bond becomes more polar. This is because the atom with the higher electronegativity pulls the shared electrons closer to itself, creating a partial negative charge (δ-) and leaving the other atom with a partial positive charge (δ+). This results in an uneven distribution of charge, making the molecule more polar.
