Let's start by examining each of the given chemical formulas and identifying the structural formula for each one.
1. [tex]\[CH_2Cl_2\][/tex]:
- This chemical formula represents dichloromethane, which contains one carbon (C) atom, two hydrogen (H) atoms, and two chlorine (Cl) atoms.
- The structure is:
```
Cl
|
H - C - H
|
Cl
```
2. [tex]\[C_2H_6O\][/tex]:
- This formula can either represent ethanol or dimethyl ether. Both have two carbon (C) atoms, six hydrogen (H) atoms, and one oxygen (O) atom.
- For ethanol, the structure is:
```
H H
| |
H - C - C - O - H
|
H
```
- For dimethyl ether, the structure is:
```
H H
\ /
C - O - C
/ \
H H
```
3. [tex]\[C_2H_6O_2\][/tex]:
- This chemical formula represents ethylene glycol, which contains two carbon (C) atoms, six hydrogen (H) atoms, and two oxygen (O) atoms.
- The structure is:
```
H H
| |
H - C - C - H
| |
O - H
|
H
```
4. [tex]\[H_2CO_3\][/tex]:
- This chemical formula represents carbonic acid, which contains two hydrogen (H) atoms, one carbon (C) atom, and three oxygen (O) atoms.
- The structure is:
```
H
\
O - C - OH
||
O
```
We've matched each chemical formula to its corresponding structural formula.
