what is the empirical formula for c₂h₆?\no ch\no ch₃\no c₂h₄\no c₆h₁₈

Answer:

B. CH₃

Explanation:

Step1: Recall empirical formula concept

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

Step2: Find ratio of C and H in C₂H₆

For C₂H₆, the ratio of C to H is 2:6. Divide both numbers by their greatest common divisor, which is 2.

Step3: Calculate simplified ratio

$\frac{2}{2}:\frac{6}{2}=1:3$. So the empirical formula is CH₃.
