Question

the ratio is very close to 1 c to 2 h. what is the empirical formula? c₂h ch₂ c₂h₂

Explanation:

Step1: Understand empirical formula concept

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

Step2: Analyze the given ratio

Given the ratio of \(C:H = 1:2\). In an empirical formula, we write the symbols of the elements with their respective sub - scripts based on the ratio. For carbon (\(C\)) with a ratio part of \(1\) and hydrogen (\(H\)) with a ratio part of \(2\), the formula is \(CH_2\).

Answer:

\(CH_2\)
