Front

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons towards itself when it is part of a compound.

Front

What partial charge does fluorine receive in HF due to its electronegativity?

Back

Fluorine receives a partial negative charge (dipole) in HF.

Front

What is the likely state of a nonpolar molecule at room temperature?

Back

Nonpolar molecules are often gases at room temperature.

Front

What is volatility in the context of substances?

Back

Volatility refers to how easily a substance can evaporate; higher volatility means it evaporates faster.

Front

Which intermolecular force is present in Cl2 molecules?

Back

Cl2 molecules exhibit dispersion forces.

Front

What type of intermolecular forces do hydrocarbons exhibit?

Back

Hydrocarbons exhibit dispersion forces.

Front

Define dispersion forces.

Back

Dispersion forces are weak intermolecular forces arising from temporary dipoles in molecules.

Front

What is a dipole-dipole interaction?

Back

Dipole-dipole interactions are forces between the positive end of one polar molecule and the negative end of another.

Front

What are hydrogen bonds?

Back

Hydrogen bonds are strong dipole-dipole interactions that occur when hydrogen is bonded to highly electronegative atoms like N, O, or F.

Front

What is the relationship between molecular size and dispersion forces?

Back

Larger molecules have stronger dispersion forces due to increased polarizability.
