Front

What is the name of the compound P₄S₅?

Back

tetraphosphorus pentasulfide

Front

What type of intermolecular force occurs in all molecules, even nonpolar ones?

Back

London Dispersion forces

Front

What is the term for the attraction between two polar molecules?

Back

Dipole Dipole

Front

What is the molecular shape of H₂S?

Back

bent

Front

Define covalent bonding.

Back

A type of chemical bond where atoms share electrons.

Front

What is VSEPR theory used for?

Back

To predict the shape of molecules based on electron repulsion.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a net dipole due to unequal sharing of electrons, while nonpolar molecules do not.

Front

What is a hydrogen bond?

Back

A strong type of dipole-dipole attraction between molecules that contain hydrogen bonded to highly electronegative atoms.

Front

What is the significance of molecular geometry in chemistry?

Back

It affects physical and chemical properties, including reactivity, polarity, and phase of matter.
