Bond Polarity

Front

What is bond polarity?

Back

Bond polarity refers to the distribution of electrical charge over the atoms joined by the bond. It occurs when there is a difference in electronegativity between the bonded atoms.

What is a polar bond?

Back

A polar bond is a type of covalent bond where the electrons are not shared equally between the two atoms, resulting in a molecule with a partially positive end and a partially negative end.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which atom is the most electronegative?

Back

Fluorine is the most electronegative atom in the periodic table.

Front

What does a single straight line represent in a Lewis structure?

Back

A single straight line in a Lewis structure represents a covalent bond, which consists of 2 electrons.

Front

What are partial charges?

Back

Partial charges are charges that occur when there is an unequal sharing of electrons in a bond, leading to a dipole moment.

Front

What is a dipole?

Back

A dipole is a separation of positive and negative charges in a molecule, often represented by partial charges.

Front

What is the difference between polar and non-polar bonds?

Back

Polar bonds have unequal sharing of electrons, resulting in partial charges, while non-polar bonds have equal sharing of electrons.

Front

What is the significance of bond polarity in molecules?

Back

Bond polarity affects the physical properties of molecules, such as solubility, boiling point, and reactivity.

Front

How does bond polarity influence molecular shape?

Back

Bond polarity can influence the shape of a molecule by affecting the angles between bonds due to repulsion between partial charges.
