Q2. Glucose (C6H12O6) could exist as both an open-chain form and a closed-ring form. Before 1900, glucose was only thought to occur as an open chain. At the present we know that over 99 percent of the time, glucose occurs in the closed-ring form. What possible dissimilarity between these forms would give chemists a clue that open-chain form was not present?
