Question
Which of the following is a molecular formula?
- HCO
- CH2O
- C6H12O6
- All the above
Hint:
The molecular formula shows the exact number of atoms in a compound.
The correct answer is: C6H12O6
The molecular formula shows the exact number of atoms in a compound.
The empirical formula of a chemical compound is the simplest whole number ratio of atoms present in a compound. HCO, CH2O are empirical formula.
C6H12O6 is a molecular formula. Sometimes empirical formula and molecular formula can be same.
