FLASHCARD QUESTION

Front

What is a non-polar molecule?

Back

A molecule that has no net dipole moment, typically because it has symmetrical charge distribution and no unbonded electron pairs.

2.

FLASHCARD QUESTION

Front

What is the role of an electronegativity chart?

Back

It is used to determine the difference in electronegativity between atoms in a bond, which helps predict bond polarity.

3.

FLASHCARD QUESTION

Front

What effect do unbonded electron pairs have on molecular polarity?

Back

Unbonded electron pairs can create a net dipole moment, making a molecule polar even if the bonds are non-polar.

4.

FLASHCARD QUESTION

Front

What is the first step in determining the polarity of a molecule?

Back

Draw the Lewis Dot structure of the molecule to visualize its shape and electron distribution.

5.

FLASHCARD QUESTION

Front

How do symmetrical dipole moments affect molecular polarity?

Back

Symmetrical dipole moments cancel each other out, resulting in a non-polar molecule.

6.

FLASHCARD QUESTION

Front

What is a dipole moment?

Back

A measure of the separation of positive and negative charges in a molecule, indicating its polarity.

7.

FLASHCARD QUESTION

Front

What is the significance of bond polarity in molecules?

Back

Bond polarity affects the overall polarity of the molecule, influencing its physical and chemical properties.
