To match the given structural formulas to their respective chemical substances, we can proceed as follows:

1. Given Structural Formula:
- [tex]\( CH_2Cl_2 \)[/tex]
- [tex]\( C_2H_6O \)[/tex]
- [tex]\( C_2H_6O_2 \)[/tex]
- [tex]\( H_2CO_3 \)[/tex]

2. Identification of Substances:

- [tex]\( CH_2Cl_2 \)[/tex]:
- This is called Dichloromethane. Its structure consists of one carbon atom (methane backbone) where two hydrogen atoms are replaced by two chlorine atoms.

- [tex]\( C_2H_6O \)[/tex]:
- This has two potential matches:
1. Ethanol: It has two carbon atoms with a single hydroxyl group (-OH) attached.
2. Dimethyl Ether: It has a structure where an oxygen atom is bound to two methyl groups (CH3).
- Both of these substances share the same molecular formula, [tex]\( C_2H_6O \)[/tex], but differ in structure (functional groups).

- [tex]\( C_2H_6O_2 \)[/tex]:
- This substance is known as Ethylene Glycol. It has a structure consisting of two carbon atoms, each bonded to a hydroxyl group (-OH).

- [tex]\( H_2CO_3 \)[/tex]:
- This is known as Carbonic Acid. It forms from carbon dioxide and water and has a structure central to the carbon atom with three oxygens, which includes a double bond to one oxygen and two OH groups more loosely connected.

3. Matching the Structural Formulas to the Chemical Substances:

- [tex]\( CH_2Cl_2 \)[/tex] corresponds to Dichloromethane.
- [tex]\( C_2H_6O \)[/tex] corresponds to Ethanol or Dimethyl Ether.
- [tex]\( C_2H_6O_2 \)[/tex] corresponds to Ethylene Glycol.
- [tex]\( H_2CO_3 \)[/tex] corresponds to Carbonic Acid.

This matching technique ensures that each structural formula is correctly identified with its respective chemical name based on the given chemical formulas.
