Molecular Geometry

Front

In covalent bonds, electrons are ___________.

Back

shared

Front

Choose the correct shape for a molecule with three bonding pairs and no lone pairs.

Back

Trigonal planar

Front

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

Back

Bent or angular

Front

Choose the correct shape for a molecule with four bonding pairs and no lone pairs.

Back

Tetrahedral

Front

What geometry will the molecular structure of H2S have?

Back

Bent

Front

Define molecular geometry.

Back

The three-dimensional arrangement of atoms in a molecule.

Front

What is the VSEPR theory?

Back

Valence Shell Electron Pair Repulsion theory; it predicts the shape of molecules based on electron pair repulsion.

Front

What is a lone pair in molecular geometry?

Back

A pair of valence electrons that are not shared with another atom.

Front

How does the presence of lone pairs affect molecular shape?

Back

Lone pairs repel more strongly than bonding pairs, altering the geometry.

Front

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

Back

Bent or angular.
