When D-Glucose is treated with concentrated HNO ₃ , it yields compound P. Separately, when D-Glucose is treated with Bromine water, it yields compound Q. The sum of the number of oxygen atoms present in one molecule of P and one molecule of Q is:

Step-by-step solution

The molecular formula of D-Glucose is C ₆ H ₁₂ O ₆ . When D-Glucose is treated with concentrated HNO ₃ , both the aldehyde group and the terminal primary alcohol group are oxidized to carboxylic acid groups, forming saccharic acid (compound P). The structure of saccharic acid is HOOC - (CHOH) ₄- COOH . The number of oxygen atoms in one molecule of P is 2 + 4 + 2 = 8 . When D-Glucose is treated with Bromine water, only the aldehyde group is oxidized to a carboxylic acid group, forming gluconic acid (compound Q). The
