You have access to this article. Flying—wedge representation 3-D representation. Fischer projection into flying wedge and vice-versa. We draw the bonds which are towards the observer by solid wedge and the bonds away from observer by dashed lines.
Then the above shown molecule becomes. We want to convert this molecule into flying wedge projection formula for this hold the atom C and D and starts the process of bending so that a inverted V is formed i. This inverted v represents the atoms in one plane. Now draw the B below this plane which is shown below in this formula.
The atom shown above is represented by above the plane in flying wedge formula. We are observing from the bottom of the right side. If we will observe from top of this molecule then we find that. Realistic representation of stereo structures of molecules. Sawhorse representation:. The sawhorse formula indicates the spatial arrangement of all the groups. The left handed bottom end represents the atom nearest to the observer and the right hand top end represents the atom away from the observer.
Newman projection: The Newman projection formula is planar projection formula of the sawhorse formula. Newman projection is similar to the sawhorse projection, but represents the spatial arrangements of all the groups on the two carbon atoms. Here, a molecule is viewed along the axis of a carbon —carbon bond. The carbon towards the front is represented by a dot.
Conversion of fischer projection into sawhorse and newman formula. When we observe the molecule from the bottom of the right side, the bond between the adjacent carbon atoms is represented by a diagonal line usually from the lower left to the upper right.
If we want to convert eclipsed form of flying wedge projection into staggered form then hold C2 atom in hand in its position and rotate the C3 atom by 0. The atoms which are towards the observer are away from the observer and the atoms which are away from the observer becomes towards the observer. Welcome Back. Continue with Google.
