Introduction
In organic chemistry, cis/trans isomerism (also known as geometric isomerism) is a form of stereoisomerism describing the relative orientation of functional groups within a molecule.
Pre-Requisites:
Isomerism In Coordination Compounds
Activity:
DNA.
Real Life Question:
What are isomers?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Optical isomerism | Optical isomerism is a form of stereoisomerism. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Isomerization | Isomerization is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms are rearranged. |
Real life uses :
Where the atoms making up the various isomers are joined up in a different order, this is known as structural isomerism.
Places to visit :
Chemistry laboratory.
Practical examples around us
| Examples | Explainations |
|---|---|
| Propanol | It has the formula C3H8O (or C3H7OH) and occurs as two isomers: propan-1-ol (n-propyl alcohol; I) and propan-2-ol (isopropyl alcohol; II) |
What you learn in Theory:
The examples of organic optical isomers required at A' level all contain a carbon atom joined to four different groups. These two models each have the same groups joined to the central carbon atom, but still manage to be different.
What you learn in Practice:
The atoms making up the isomers are joined up in the same order, but still manage to have a different spatial arrangement. Optical isomerism is one form of stereoisomerism.
