Textbook Question

Which electronegativity difference (a, b, or c) would you expect for a nonpolar covalent bond? a. from 0.0 to 0.4 b. from 0.5 to 1.8 c. from 1.9 to 3.3

Verified step by step guidance

Identify the concept of electronegativity: Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Understand the types of bonds: Nonpolar covalent bonds occur when two atoms share electrons equally, typically between atoms with similar electronegativities.

Review the electronegativity difference ranges: Nonpolar covalent bonds have an electronegativity difference close to zero.

Analyze the given options: Compare the electronegativity difference ranges provided in options a, b, and c.

Determine which range corresponds to a nonpolar covalent bond: Look for the range that indicates a minimal difference in electronegativity, suggesting equal sharing of electrons.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Electronegativity

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond. It is a key factor in determining the nature of the bond formed between two atoms. The higher the electronegativity, the stronger the atom's pull on shared electrons, influencing whether a bond is polar or nonpolar.

Covalent Bonds

Covalent bonds are formed when two atoms share one or more pairs of electrons. The nature of the bond—whether it is polar or nonpolar—depends on the difference in electronegativity between the bonded atoms. Nonpolar covalent bonds occur when the electronegativity difference is minimal, allowing for equal sharing of electrons.

Electronegativity Difference

The electronegativity difference between two atoms determines the type of bond they will form. A difference of 0.0 to 0.4 typically indicates a nonpolar covalent bond, where electrons are shared equally. In contrast, larger differences lead to polar covalent or ionic bonds, where electron sharing is unequal or one atom completely transfers electrons to another.
