Properties of Polar and Nonpolar Molecules

Front

What is the location of atoms with the lowest electronegativity values on the periodic table?

Back

Lower left corner of the periodic table.

Front

What type of bond is likely to form if the electronegativity difference between two atoms is greater than 2.1?

Back

Ionic bond.

Front

What is true about the partial charges in water molecules?

Back

The partial negative charge is on the oxygen atom and there is a strong intermolecular force between the water molecules.

Front

Why are diatomic molecules like H₂, Cl₂, and N₂ always nonpolar?

Back

The two atoms have the same electronegativity.

Front

Which statement is not true about polar molecules?

Back

Polar molecules are repelled by each other.

Front

Define polar molecules.

Back

Molecules that have a partial positive charge on one side and a partial negative charge on the other due to an uneven distribution of electrons.

Front

What is electronegativity?

Back

The tendency of an atom to attract electrons in a chemical bond.

Front

What type of bond is formed between atoms with similar electronegativities?

Back

Nonpolar covalent bond.

Front

What is a characteristic of ionic bonds?

Back

They form between atoms with a large difference in electronegativity, typically greater than 1.7.

Front

What is the significance of lone pairs in determining molecular polarity?

Back

Lone pairs can create an uneven distribution of charge, contributing to molecular polarity.
