Interpretation:
The given Haworth projection should be converted into an open-chain form and to Fischer projections. Also, name the monosaccharide so formed.
Concept Introduction:
A Haworth projection is a way to write structral fornula that reprsents the cyclic structure of a monosaccharide. There are following characteristics a Haworth projection should have:
In the Haworth projection, for six carbon atoms, the
The Fischer projection is two dimensional representation of the three-dimensional projection. It is used to differentiate between D and L molecules. In the D configuration, the carbon next to the last has hydrogen on the left and hydroxyl group on the right whereas in L configuration, the hydrogen is on the right a hydroxyl group on the left.
All the horizontal bonds in the Fischer projection are directed towards the viewer and vertical bonds are directed away from the viewer.

Concept Introduction:
A Haworth projection is a way to write structral fornula that reprsents the cyclic structure of a monosaccharide. There are following characteristics a Haworth projection should have:
In the Haworth projection, for six carbon atoms, the atoms are numbered from 1 to 6 and carbon 1 is known as anomeric carbon. The ticker line denotes the atoms closer to the observer and thiner lines denotes the atoms away from the observer.

Generate a molecular orbital diagram but this time using a different approach that draws on your knowledge and ability to put concepts together. First use VSEPR or some other method to make sure you know the ground state structure of the molecule. Next, generate an MO diagram for BH2. Sketch the highest occupied and lowest unoccupied MOs of the BH2 fragment. These are called frontier orbitals. Now use these frontier orbitals as your basis set for producing LGO's for B2H6. Since the BH2 frontier orbitals become the LGOS, you will have to think about what is in the middle of the molecule and treat its basis as well. Do you arrive at the same qualitative MO diagram as is discussed in the book? Sketch the new highest occupied and lowest unoccupied MOs for the molecule (B2H6).arrow_forward
