Answer

Explanation:

Step1: Determine empirical formula concept

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

Step2: Count atoms in Compound A

Count C, H, and O atoms. Assume the structure of Compound A has 4 C, 10 H, 2 O. The ratio of C : H : O is 4:10:2, which simplifies to 2:5:1. The empirical formula is $C_2H_5O$.

Step3: Count atoms in Compound B

Count C, H, and O atoms. Assume the structure of Compound B has 4 C, 10 H, 4 O. The ratio of C : H : O is 4:10:4, which simplifies to 2:5:2. The empirical formula is $C_2H_5O_2$.

Step4: Count atoms in Compound C

Count C, H, and O atoms. Assume the structure of Compound C has 2 C, 4 H, 1 O. The ratio of C : H : O is 2:4:1. The empirical formula is $C_2H_4O$.

Step5: Group compounds

Since all three compounds have different empirical formulas, Compound A is in Group 1, Compound B is in Group 2, Compound C is in Group 3.

Answer:

Compound A: Group 1 Compound B: Group 2 Compound C: Group 3
