Hold your eye up to your model of ethane to simulate the perspective shown by the Newman projection in Figure. 6.1.

As you can see we have two different ways for the Newman Projection. In the left case the black hydrogen on the left side is pointed up, thus the other one on the right side is pointed down. Wedged bond means the bond is pointing towards us, the dashed bond means the bond is extending behind the plane of the drawing surface.Exercise 25.3.1 25.3. 1.

The decreasing order of the oxidised state of some common group is as follows: -COOH > -CHO > -CH 2 -OH > -CH 3. Characteristics Features of Fischer Projection: These Projections are particularly useful for representing stereocenters and chiral molecules.

Much like the Dash-Wedge representation, the Newman projection precludes that the spatial arrangement of atoms and molecules within the compound is dependent upon the specific bonds linking these groups and the relative position (i.e., bond angle) of these bonds in relation to the entire compound. In other words, as full rotation around the ...

The gauche interaction occurs in butane occurs when the two methyl groups have dihedral angles of 60° and 300° and arises because the methyl groups are still quite close together (about 3.1 Å, compare to 2.9 Å) for the syn – conformation. The strain energy of the gauche interaction is about 0.9 kcal/mol.
