Final answer:
To complete the Haworth projection of α‑D‑galactose, place labels on the pyranose ring indicating the positions of the hydroxyl groups. The hydroxyl groups in α‑D‑galactose are attached to the second, third, and fourth carbons of the ring.
Step-by-step explanation:
The Haworth projection of α‑D‑galactose can be completed by placing labels on the pyranose ring. The labels should indicate the positions of the hydroxyl groups on the ring. In α‑D‑galactose, the hydroxyl groups are attached to the second, third, and fourth carbons of the ring. The oxygen of the hydroxyl groups should be next to the bond.
