Unit 2 Exam 1 Review 2

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 geometry is associated with CF4?

Back

CF4 has a tetrahedral molecular geometry.

Front

What is the molecular geometry of PCl3?

Back

PCl3 has a trigonal pyramidal molecular geometry.

Front

Which molecule has a bent shape?

Back

H2O (water) has a bent molecular shape due to the two lone pairs of electrons on the oxygen atom.

Front

What is the bond angle in a trigonal planar molecule?

Back

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

Front

What is the molecular geometry of BF3?

Back

BF3 has a trigonal planar molecular geometry.

Front

How do lone pairs affect molecular geometry?

Back

Lone pairs repel more strongly than bonding pairs, which can distort bond angles and affect the overall shape of the molecule.

Front

What is the difference between molecular geometry and electron geometry?

Back

Molecular geometry refers to the arrangement of atoms in a molecule, while electron geometry considers the spatial arrangement of all electron pairs (bonding and lone pairs).

Front

What is the molecular shape of SCl4?

Back

SCl4 has a seesaw molecular shape due to the presence of one lone pair.

Front

Which of the following has the same molecular geometry: PCl3 and NBr3?

Back

PCl3 and NBr3 both have a trigonal pyramidal molecular geometry.
