Molecular Models & Stereochemistry

One of the most boring lab ever. @_@ But quite an eye opener, however. In this lesson, we were to assemble a few models of a compound to study how their molecular structure looks like. Assembling all the balls and joints together can be quite a pain, very hard to stick and remove.

The box

All the 'toys' in it.

Methane, CH4

Ethane!

Eclipsed conformation of ethane

Staggered conformation of ethane

Butane(extended chain)

Butane(bent chain) - very unstable

Isobutane

Cyclohexane

Cyclohexane- Chair conformation i think. o_O

Mickey Mouse...?

Toluene

Orthoxylene (1,2-dimethylbenzene)

Pacaxylene (1,4-dimethylbenzene)

Ethene. It's quite obvious here that the double bonds are not freely rotatable.

Trans-2-butene

Cis-2-butene

Lactic acid

Lactic acid showing enatiomerism.

R-enantiomer and S-enantiomer

Aspirin!
