VSEPR & Molecule Polarity Practice

Front

What is VSEPR theory?

Back

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

Front

What determines if a molecule is polar?

Back

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

Front

What is a dipole moment?

Back

A dipole moment is a measure of the separation of positive and negative charges in a molecule, indicating its polarity.

Front

What is the effect of lone pairs on molecular shape?

Back

Lone pairs occupy more space than bonding pairs, which can distort the shape of the molecule.
