Question

write the empirical formula corresponding to $\ce{c6h4cl2}$

Explanation:

Step1: Find the greatest common divisor (GCD)

The sub - scripts in the formula \(C_6H_4Cl_2\) are \(6\), \(4\), and \(2\).
The factors of \(6\) are \(1,2,3,6\); the factors of \(4\) are \(1,2,4\); the factors of \(2\) are \(1,2\).
The GCD of \(6\), \(4\), and \(2\) is \(2\).

Step2: Divide each sub - script by the GCD

For \(C\): \(\frac{6}{2}=3\)
For \(H\): \(\frac{4}{2} = 2\)
For \(Cl\): \(\frac{2}{2}=1\)

Answer:

\(C_3H_2Cl\)
