Molecular geometry

Front

What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule, which influences its physical and chemical properties.

Front

What shape is formed by a molecule with two bonding pairs and no lone pairs?

Back

Linear.

Front

What shape is formed by a molecule with three bonding pairs and no lone pairs?

Back

Trigonal planar.

Front

What shape is formed by a molecule with two bonding pairs and one lone pair?

Back

Bent.

Front

What shape is formed by a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral.

Front

What is the VSEPR theory?

Back

Valence Shell Electron Pair Repulsion (VSEPR) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell.

Front

How does the presence of lone pairs affect molecular geometry?

Back

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

Front

What is the bond angle in a trigonal planar molecule?

Back

120 degrees.

Front

What is the bond angle in a tetrahedral molecule?

Back

109.5 degrees.

Front

What is the bond angle in a bent molecule with two bonding pairs and one lone pair?

Back

Less than 120 degrees.
