Certainly, let's find the empirical formulas for the given molecular formulas.
The empirical formula represents the simplest whole-number ratio of atoms in a compound. To find it, we need to divide the subscripts in the molecular formula by their greatest common divisor (GCD).
Here's the breakdown for each:
1. C₄H₈
- The subscripts are 4 and 8.
- The greatest common divisor of 4 and 8 is 4.
- Divide both subscripts by 4: C$_{\text{4/4}}$H$_{\text{8/4}}$ = CH₂
- Empirical Formula: CH₂
2. C₂H₄
- The subscripts are 2 and 4.
- The greatest common divisor of 2 and 4 is 2.
- Divide both subscripts by 2: C$_{\text{2/2}}$H$_{\text{4/2}}$ = CH₂
- Empirical Formula: CH₂
3. C₄H₂
- The subscripts are 4 and 2.
- The greatest common divisor of 4 and 2 is 2.
- Divide both subscripts by 2: C$_{\text{4/2}}$H$_{\text{2/2}}$ = C₂H
- Empirical Formula: C₂H
4. CH₄
- The subscripts are 1 and 4.
- The greatest common divisor of 1 and 4 is 1.
- Since the subscripts are already in their simplest whole-number ratio, the empirical formula is the same as the molecular formula.
- Empirical Formula: CH₄
