Question

approximately in which range of electronegativity differences would polar covalent bonds occur? (1 point) -1.0 to 0 0 to 1.0 0.5 to 1.7 0 to 0.5

Explanation:

Polar covalent bonds occur when there is an uneven sharing of electrons between atoms. This happens when the electronegativity difference ($\Delta \text{EN}$) between the two atoms is in the range where one atom has a stronger pull on the shared electrons than the other, but not so strong that it completely transfers the electrons (which would form an ionic bond, $\Delta \text{EN}> 1.7$). A $\Delta \text{EN}$ of $0$ indicates a non - polar covalent bond (equal sharing of electrons). For polar covalent bonds, the range of electronegativity differences is $0.5$ to $1.7$.

Answer:

$0.5$ to $1.7$
