Polarity Practice

Front

What does the symbol above F in a Lewis structure indicate?

Back

Electrons are more attracted to F than H.

Front

Is the molecule with a dipole moment considered polar or non-polar?

Back

Polar.

Front

What type of bond forms when Bromine bonds with Hydrogen?

Back

Polar covalent.

Front

What is the molecular geometry of PH3?

Back

Trigonal pyramidal.

Front

Which molecule has bonds of greater polarity: H2O or OF2?

Back

H2O.

Front

Define polarity in the context of molecular chemistry.

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond.

Front

What is a polar covalent bond?

Back

A bond where electrons are shared unequally between two atoms, resulting in a dipole moment.

Front

What is the significance of electronegativity in determining bond polarity?

Back

Electronegativity is the ability of an atom to attract electrons; greater differences in electronegativity between bonded atoms lead to more polar bonds.

Front

What is the molecular shape of a molecule with two bonding pairs and one lone pair?

Back

Bent.

Front

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

Back

By assessing the symmetry of the molecule and the polarity of its bonds.
