8th - VSEPR & Hybridization Practice [Honors/IH]

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 molecular shape is formed when there are two bonding pairs and one lone pair of electrons?

Back

The molecular shape is bent.

Front

What is the molecular geometry of a molecule with four bonding pairs and no lone pairs?

Back

The molecular geometry is tetrahedral.

Front

How does the presence of lone pairs affect molecular shape?

Back

Lone pairs repel more strongly than bonding pairs, which can alter the angles between bonding pairs and change the overall shape of the molecule.

Front

What is the molecular shape of BCl3?

Back

The molecular shape of BCl3 is trigonal planar.

Front

What is the difference between molecular geometry and electron geometry?

Back

Molecular geometry refers to the arrangement of only the bonding pairs of electrons, while electron geometry considers both bonding and lone pairs.

Front

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

Back

The electron geometry is tetrahedral.

Front

What is the significance of bond angles in molecular geometry?

Back

Bond angles are important as they determine the spatial arrangement of atoms in a molecule, which affects its reactivity and properties.

Front

What molecular shape is associated with a central atom that has three bonding pairs and one lone pair?

Back

The molecular shape is trigonal pyramidal.

Front

What is the bond angle in a trigonal planar molecule?

Back

The bond angle in a trigonal planar molecule is approximately 120 degrees.
