VisChem topic 6: molecular structure, shape and polarity

This web page contains ten animations of molecules and compound ions as well as nine QTVR objects showing organic molecules. The animations rotate the molecules to show their structure fully. The QTVR objects can be manipulated by the user so that, as well as being rotated, different ways of modelling the molecules can be seen.

VisChem topic 7: intermolecular forces

This web page contains animations demonstrating situations in which dispersion forces, ion-dipole forces and hydrogen bonding occur. Several animations show hydrated ions, and the effect of hydration on dissolving and reaction rates is discussed in explanatory text. A document containing lesson plans and student worksheets ...

VisChem topic 12: acid-base reactions

This web page contains a video, animations and a student worksheet examining the proton-transfer reactions of acids and bases. Self-ionisation of water, acidity of hydrated metal ions, proton gain by ammonia molecules and proton loss from acetic acid are depicted. The animations show important molecular-level segments from ...

Water molecule showing polarity

This is a colour graphic representation of a water molecule. It depicts the structural formula of water superimposed on a space-filling model and an electron-density isosurface. The diagram is colour-coded to show the dipole nature of the molecule.

Image

Water molecule

This is a colour image of a model of a molecule of water, H₂O. In this model, atoms are represented by coloured spheres held together by grey rods, representing covalent bonds. The water molecule contains one oxygen atom (the red sphere) and two hydrogen atoms (the grey-white spheres).

Image

Ammonia molecule

This is a colour image of a model of a molecule of ammonia, NH₃. In this model, atoms are represented by coloured spheres held together by grey rods, representing covalent bonds. The ammonia molecule consists of one nitrogen atom (the blue sphere) and three hydrogen atoms (the grey-white spheres).

Image

Ethanol molecule

This is a colour image of a model of a molecule of ethanol, CH₃CH₂OH. In this model, atoms are represented by coloured spheres held together by grey rods that represent covalent bonds. The molecule contains two carbon atoms (the black spheres), one oxygen atom (the red sphere) and six hydrogen atoms (the grey-white spheres).

Image

Iodine molecule

This is a colour image of a model of a molecule of iodine, I₂. In this model, two iodine atoms are represented by deep red spheres held together by a grey rod that represents a covalent bond.

Image

Hydrogen molecule

This is a colour image of a model of a molecule of hydrogen, H₂. In this model, two hydrogen atoms are represented by grey-white spheres held together by a grey rod that represents a covalent bond.

Image

Oxygen molecule

This is a colour image of a model of a molecule of oxygen, O₂. In this model, two oxygen atoms are represented by red spheres held together by grey rods that represent a double covalent bond.

Image

Carbon dioxide molecule

This is a colour image of a model of a molecule of carbon dioxide, CO₂. In this model, atoms are represented by coloured spheres held together by grey rods that represent covalent bonds. The molecule contains one carbon atom (the black sphere) and two oxygen atoms (the red spheres).
