Question
Which of the following is NOT an empirical formula?
A. CH₂
B. CH₂O
C. C₂H₄N₂
D. C₃H₆O₂
Solution
The empirical formula of a compound represents the simplest whole-number ratio of the atoms in the compound.
Let's examine each option:
A. CH2: This is an empirical formula. It cannot be simplified further.
B. CH2O: This is also an empirical formula. It cannot be simplified further.
C. C2H4N2: This is an empirical formula. It cannot be simplified further.
D. C3H6O2: This is not an empirical formula. It can be simplified to CH2O.
So, the answer is D. C3H6O2.
