What is the empirical formula of glucose (C6H12O6)?
A
CHO
B
C3H6O3
C
C6H12O6
D
CH2O
Correct Answer: Option D — CH2O
Explanation:
The empirical formula represents the simplest whole-number ratio of atoms, so dividing all subscripts of glucose by 6 gives CH2O, though the actual molecular formula remains C6H12O6.
