Molecular Geometry II

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 shape does a molecule with four bonding pairs and no lone pairs have?

Back

Tetrahedral.

Front

In covalent bonds, how are electrons shared?

Back

Electrons are shared equally or unequally between atoms, depending on their electronegativity.

Front

What is the shape of a molecule with two bonding pairs and two lone pairs?

Back

Bent.

Front

What is the molecular shape of carbon dioxide (CO2)?

Back

Linear.

Front

What is the shape of ammonia (NH3)?

Back

Trigonal pyramidal.

Front

What is the VSEPR theory?

Back

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

Front

What is a lone pair of electrons?

Back

A lone pair is a pair of valence electrons that are not shared with another atom and are localized on a single atom.

Front

How does electronegativity affect molecular shape?

Back

Electronegativity differences can lead to polar bonds, affecting the overall shape and polarity of the molecule.

Front

What is the shape of methane (CH4)?

Back

Tetrahedral.
