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.
