6th - 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 is hybridization in chemistry?

Back

Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals, which can then form bonds with other atoms.

Front

What is the molecular shape of a molecule with sp³ hybridization?

Back

The molecular shape is typically tetrahedral.

Front

What is the bond angle in a trigonal planar molecule?

Back

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

Front

What is the bond angle for a bent molecular shape?

Back

The bond angle for a bent molecular shape is approximately 104.5 degrees.

Front

What type of hybridization is found in a molecule with a trigonal planar shape?

Back

The hybridization is sp² hybridization.

Front

How does VSEPR theory help in molecular geometry?

Back

VSEPR theory helps in determining the shape and geometry of a molecule by considering the number of bonding and lone pairs of electrons around the central atom.

Front

What is the molecular shape of BCl₃?

Back

The molecular shape of BCl₃ is trigonal planar.

Front

What is the hybridization of a molecule with a tetrahedral shape?

Back

The hybridization is sp³ hybridization.

Front

What is the significance of lone pairs in VSEPR theory?

Back

Lone pairs occupy space and can affect the bond angles and overall shape of the molecule.
