Inter & Intra Molecular Forces

Front

What are intermolecular forces?

Back

Intermolecular forces are forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions). They play a crucial role in determining the physical properties of substances.

Front

What is the difference between intermolecular and intramolecular forces?

Back

Intermolecular forces occur between molecules, while intramolecular forces occur within a molecule, holding the atoms together.

Front

Define dipole-dipole forces.

Back

Dipole-dipole forces are intermolecular forces that occur between polar molecules, where the positive end of one molecule is attracted to the negative end of another.

Front

What is hydrogen bonding?

Back

Hydrogen bonding is a strong type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like fluorine, oxygen, or nitrogen.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules, occurring in all molecules, whether polar or nonpolar.

Front

What is the significance of valence electrons?

Back

Valence electrons are the outermost electrons of an atom and are crucial for determining how an atom will bond with others.

Front

How does electronegativity affect bond type?

Back

Electronegativity differences between atoms determine the type of bond formed: ionic (large difference), polar covalent (moderate difference), or non-polar covalent (small or no difference).

Front

Why does water have a high boiling point?

Back

Water has a high boiling point due to hydrogen bonding, which requires more energy to break compared to other intermolecular forces.

Front

What is the phrase used to remember hydrogen bonding?

Back

Hydrogen just wants to have FON (Fluorine, Oxygen, Nitrogen).

Front

What are ionic bonds?

Back

Ionic bonds are formed when one atom donates an electron to another, resulting in the attraction between positively and negatively charged ions.
