The number of chiral centers in the open chain structure of glucose is______

Answer

4

Explanation

Open chain structure of glucose is `underset(underset(underset(underset(underset(underset(CH_(2)OH)(|))(H- C^(**) - OH))(|))(H- C^(**)- OH))(|))overset(overset(overset(overset(CHO)(|))(H-C^(**)-OH))(|))(HO - C^(**) - H)`
