Molecular Polarity

Front

What determines the polarity of a bond?

Back

The difference in the electronegativities of the two atoms.

Front

Which atom is the most electronegative in the periodic table?

Back

Fluorine.

Front

What type of molecule is O2 and why?

Back

O2 is a nonpolar molecule because electrons are shared equally.

Front

How can you determine if a molecule is polar or non-polar?

Back

By analyzing the distribution of electron density and the shape of the molecule.

Front

In a polar covalent bond, where do the electrons tend to gather?

Back

Around the atom with the greatest electronegativity.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What is a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds that do not cancel each other out.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule has no net dipole moment, often due to symmetrical distribution of charge.

Front

What is the significance of bond polarity in chemical reactions?

Back

Bond polarity affects the reactivity, solubility, and boiling/melting points of substances.

Front

How does molecular shape influence polarity?

Back

The shape of a molecule determines how dipoles from polar bonds add up, affecting overall polarity.
