what is the empirical formula for propene (c3h6)?\no c2h4\no c4h8\no c3h6\no ch2

Explanation:

Step1: Recall empirical formula concept

The empirical formula is the simplest whole - number ratio of atoms in a compound.

Step2: Find ratio for $C_3H_6$

For $C_3H_6$, divide the sub - scripts of carbon and hydrogen by their greatest common divisor. The greatest common divisor of 3 and 6 is 3. $\frac{3}{3}=1$ for carbon and $\frac{6}{3}=2$ for hydrogen. So the empirical formula is $CH_2$.

Answer:

D. $CH_2$
