match each molecular formula to the corresponding empirical formula. c₄h₈o₂ c₄h₁₂o₄ c₂h₁₀o₂ ch₃o ch₅o c₂h₄o…

Answer:

$CH_3O$ → $C_4H_{12}O_4$ $CH_5O$ → $C_2H_{10}O_2$ $C_2H_4O$ → $C_4H_8O_2$

Explanation:

Step1: Find ratio for $C_4H_{12}O_4$

Divide sub - scripts by 4. $\frac{4}{4}:\frac{12}{4}:\frac{4}{4}=1:3:1$, empirical formula is $CH_3O$.

Step2: Find ratio for $C_2H_{10}O_2$

Divide sub - scripts by 2. $\frac{2}{2}:\frac{10}{2}:\frac{2}{2}=1:5:1$, empirical formula is $CH_5O$.

Step3: Find ratio for $C_4H_8O_2$

Divide sub - scripts by 2. $\frac{4}{2}:\frac{8}{2}:\frac{2}{2}=2:4:1$, empirical formula is $C_2H_4O$.
