Molecular Geometry & IMFs

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.

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds and an asymmetrical shape, resulting in a positive and negative end.

Front

What is the effect of lone pairs on bond angles?

Back

Lone pairs decrease bond angles because they occupy more space than bonded electrons, pushing the bonded atoms closer together.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules, present in all molecular substances.

Front

What factors affect the polarity of a molecule?

Back

The polarity of a molecule is affected by asymmetry in its shape and the presence of lone pairs of electrons on the central atom.

Front

What is a double bond?

Back

A double bond is a type of chemical bond where two pairs of electrons are shared between two atoms, resulting in a stronger bond than a single bond.

Front

What is the difference between polar and nonpolar bonds?

Back

Polar bonds occur when there is an unequal sharing of electrons between atoms, while nonpolar bonds involve equal sharing of electrons.

Front

What is the VSEPR theory?

Back

The Valence Shell Electron Pair Repulsion (VSEPR) theory predicts the shape of molecules based on the repulsion between electron pairs around a central atom.

Front

What is a dipole-dipole interaction?

Back

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

Front

What is the significance of symmetry in molecular geometry?

Back

Symmetry in molecular geometry often leads to nonpolar molecules, as the dipoles can cancel each other out.
