Question

determine the empirical formula from the molecular formula, c₆h₁₂o₆.
a ch₂o
b c₃h₆o₃
c c₄h₈o₄
d c₆h₁₂o₆
e c₂h₄o₂

Explanation:

Step1: Find GCD of subscripts

For \( C_6H_{12}O_6 \), find GCD of 6, 12, 6. GCD(6,12,6) = 6.

Step2: Divide subscripts by GCD

Divide each subscript by 6: \( C_{\frac{6}{6}}H_{\frac{12}{6}}O_{\frac{6}{6}} = CH_2O \).

Answer:

a. \( CH_2O \)
