How can covalent bonds be categorized based on polarity?
Understand the Problem
The question is asking how to classify covalent bonds in relation to their polarity. It presents multiple-choice options, and the user needs to identify which option correctly describes this categorization based on the concept of electronegativity differences between atoms involved in the bond.
Answer
Covalent bonds are categorized as polar or nonpolar based on electron distribution.
Covalent bonds can be categorized based on polarity into polar and nonpolar covalent bonds. Polar covalent bonds have an uneven distribution of electron charge due to a difference in electronegativity between the atoms, while nonpolar covalent bonds have equal sharing of electrons.
Answer for screen readers
Covalent bonds can be categorized based on polarity into polar and nonpolar covalent bonds. Polar covalent bonds have an uneven distribution of electron charge due to a difference in electronegativity between the atoms, while nonpolar covalent bonds have equal sharing of electrons.
More Information
The polarity of a covalent bond affects the molecule's physical properties, such as boiling and melting points, solubility, and its chemical reactivity.
Tips
A common mistake is confusing polar covalent bonds with ionic bonds. Make sure to check the electronegativity difference: polar covalent bonds have a moderate difference, not as high as in ionic bonds.
