Answer

Explanation:

Step1: Determine empirical formula of Compound A

Count atoms: C - 4, H - 10, O - 2. Empirical formula is $C_{2}H_{5}O$.

Step2: Determine empirical formula of Compound B

Count atoms: C - 4, H - 8, O - 4. Empirical formula is $CH_{2}O$.

Step3: Determine empirical formula of Compound C

Count atoms: C - 2, H - 4, O - 1. Empirical formula is $C_{2}H_{4}O$.

Step4: Determine empirical formula of Compound D

Count atoms: C - 3, H - 4, O - 3. Empirical formula is $C_{3}H_{4}O_{3}$.

Step5: Group compounds

Since all have different empirical formulas, they are in separate groups.

Answer:

Compound A: Group 1 Compound B: Group 2 Compound C: Group 3 Compound D: Group 4
