Molecular Geometry and Polarity

Front

What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule, which affects its physical and chemical properties.

What is the VSEPR theory?

Back

The Valence Shell Electron Pair Repulsion (VSEPR) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell of the central atom.

What is the molecular geometry of KrF4?

Back

Square planar.

Front

What is the molecular geometry of SF6?

Back

Octahedral.

Front

What is the molecular geometry of PI3?

Back

Trigonal pyramidal.

Front

What determines the polarity of a molecule?

Back

The polarity of a molecule is determined by the difference in electronegativity between the atoms and the shape of the molecule.

Front

What is a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds and an asymmetrical shape.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule has no net dipole moment, often due to symmetrical shape and equal sharing of electrons.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

Which atom has a stronger pull on shared electrons in HCl?

Back

Cl has a stronger pull on the shared electrons due to its higher electronegativity.
