Lewis structures, polarity, IMFs

Front

What is a Lewis dot structure?

Back

A Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

How many valence electrons does fluorine (F) have?

Back

Fluorine has 7 valence electrons.

Front

What is the total number of valence electrons in the nitrate ion (NO3-)?

Back

The nitrate ion (NO3-) has a total of 24 valence electrons.

Front

What is the strongest type of bond among covalent bonds, hydrogen bonds, dipole-dipole attractions, and London dispersion forces?

Back

Covalent bonds are the strongest type of bond among these.

Front

What determines if a molecule is polar or non-polar?

Back

A molecule is polar if it has a net dipole moment due to the arrangement of its polar bonds and the shape of the molecule.

Front

What type of intermolecular force is present in HCl?

Back

HCl exhibits dipole-dipole intermolecular forces.

Front

What is a polar molecule?

Back

A polar molecule is one that has a partial positive charge on one end and a partial negative charge on the other end due to unequal sharing of electrons.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules.

Front

What is a hydrogen bond?

Back

A hydrogen bond is a strong type of dipole-dipole attraction that occurs between a hydrogen atom bonded to a highly electronegative atom and another electronegative atom.

Front

How do you determine the polarity of a molecule?

Back

To determine polarity, assess the electronegativity differences between atoms and the molecular geometry.
