1. If the diatomic molecule’s bond is polar, it is polar. 2. The polarity of the molecule has a significant impact on physical properties such as boiling point. Answer: Both the statements are true. Explanation: If the bond between the bonded atoms is polar, the molecule is said to be polar.
molecular compounds often have properties unmatched by ionic compounds. For instance, at room temperature, methane is a gas and water is liquid. What accounts for these similarities and difference? A critical part of the answer to this question begins with understanding the nature of polar bonds and polar molecules.
Answer nonpolar covalent: electronegativity difference is less than 0.4 (nonmetal+nonmetal close together on the periodic table) polar covalent: electronegativity difference in between 0.4 and 2.0 (nonmetal + nonmental further apart on the periodic table)
Using the electronegativity values in Figure \(\PageIndex{3}\), arrange the bonds in order of increasing polarity and designate the positive and negative atoms using the symbols δ+ and δ–. Answer Bond
When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity.
