Fischer Projection to Bond Line View
Key Questions
-
Answer:
You draw a zig-zag line with the correct number of carbon atoms, then you attach the groups in the correct locations.
Explanation:
For example, the Fischer projection of D-gulose is
To convert the Fischer projection to a bond line formula you just draw a zig-zag line of six carbon atoms.
Then you put an aldehyde group at
#"C-1"# and an#"OH"# group on each of the other five carbon atoms.You get
(from www.chemeddl.org)Note that a bond line formula gives no stereochemical information.
It shows only which atoms are connected to the other atoms.
The structure above could represent any of the fifteen stereoisomers of D-gulose.

Answer:
It is useful to convert Fischer projections to bond line views when you want to show the basic structure of the molecule without any stereochemical information.

Answer:
A bond-line view is a condensed way of representing the structural formula of a molecule.
Explanation:
For example, here is the structural formula of retinol, a compound that is important in the chemistry of vision.
It takes a long time to write out all these atoms and bonds, so chemists have developed a shorthand method called a bond-line view.
The rules for drawing bond-line structures are:
- The carbon atoms and the hydrogen atoms attached to them are not shown.
- Only the bonds between the carbon atoms are shown as lines.
- The vertices and end of lines represent carbon atoms.
- Any unfilled valences on carbon are assumed to be filled by hydrogen atoms.
- All atoms other than carbon, plus any hydrogen atoms attached to them, are shown.
- Exception: The hydrogen in an aldehyde group is usually shown.
