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, resulting in a partial positive charge on one end and a partial negative charge on the other.

Front

What is the shape of a tetrahedral molecule?

Back

A tetrahedral molecule has a central atom bonded to four other atoms, with bond angles of approximately 109.5 degrees.

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

How do lone pairs of electrons affect molecular geometry?

Back

Lone pairs of electrons occupy more space than bonded pairs, which can decrease bond angles and alter the overall shape of the molecule.

Front

Which element is most likely to be the central atom in Lewis structures?

Back

Carbon (C) is most likely to be the central atom in Lewis structures due to its ability to form four bonds.

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 the significance of bond angles in molecular geometry?

Back

Bond angles are significant because they influence the shape of the molecule, which in turn affects its reactivity and interactions with other molecules.

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 a Lewis structure?

Back

A Lewis structure is a diagram that represents the bonding between atoms in a molecule and the lone pairs of electrons that may exist.
