MOLECULAR GEOMETRY

Front

What is the shape of a molecule with a trigonal planar geometry?

Back

A trigonal planar molecule has three atoms bonded to a central atom, arranged in a flat, triangular shape with bond angles of 120 degrees.

Front

According to VSEPR theory, what do molecules adjust their shapes to minimize?

Back

Molecules adjust their shapes to keep pairs of valence electrons as far away from each other as possible.

Front

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

Back

A tetrahedral molecule has four atoms bonded to a central atom, arranged in a three-dimensional shape with bond angles of approximately 109.5 degrees.

Front

Define a lone (unshared) pair of electrons.

Back

A lone pair is a pair of non-bonding electrons that are localized on a single atom and not involved in bonding.

Front

What best describes a triple bond?

Back

A triple bond consists of three shared pairs of electrons between two atoms.

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 molecular geometry of a molecule with two bonding pairs and one lone pair?

Back

The molecular geometry is bent.

Front

How many total electron pairs are involved in a tetrahedral molecular geometry?

Back

There are four total electron pairs in a tetrahedral molecular geometry.

Front

What is the difference between a single bond and a double bond?

Back

A single bond involves one shared pair of electrons, while a double bond involves two shared pairs of electrons.

Front

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

Back

The molecular shape is tetrahedral.
