Question #a49f8

Answer 1

The Haworth projection for α-D-glucose is

Explanation:

1. A chiral carbon has four different groups attached.

α-D-Glucose has no plane of symmetry, so all the carbon atoms are different.

There are five chiral carbons: `"C-1, C-2, C-3, C-4"`, and `"C-5"`.

2. Three hydroxyl groups are below the plane of the ring.

3. `bb"C-5"` is attached to an oxygen within the ring and a carbon (`"C-6"`) outside the ring.

4. Three of the ring hydrogens (on `"C-1, C-2"`, and `"C-4"`) are above the plane of the ring, and two (on `"C-3"` and `"C-5"`) are below the plane of the ring.
