Which of the following is the empirical formula of C_3H_6?

• A. C_3H_6
• B. CH_2
• C. C_6H_{12}
• D. C_2H_4

Answer: (B)

Verified step by step guidance

1. Identify the molecular formula given: \(C_3H_6\).
2. Determine the ratio of atoms of each element by dividing the subscripts by their greatest common divisor (GCD). For \(C_3H_6\), find the GCD of 3 and 6.
3. Divide the number of carbon atoms and hydrogen atoms by the GCD to simplify the formula to the smallest whole number ratio.
4. Write the empirical formula using the simplified ratio of atoms obtained from the previous step.
5. Compare the simplified formula to the options given to confirm which one matches the empirical formula.
