does 2 butene compound is showing geometrical isomers:

Explanation

To determine if 2-butene exhibits geometrical isomers, we can follow these steps:

### Step 1: Understand the Structure of 2-Butene
2-butene is an alkene with the formula C₄H₈. It has a double bond between the second and third carbon atoms. The structure can be represented as follows:

```
H H
\ /
C=C
/ \
CH3 CH3
```

### Step 2: Identify the Conditions for Geometrical Isomerism
Geometrical isomerism (cis-trans isomerism) occurs in alkenes when there are two different groups attached to each carbon of the double bond. In the case of 2-butene, both carbon atoms involved in the double bond (C2 and C3) have different substituents.

### Step 3: Determine the Possible Isomers
For 2-butene, we can have:
- **Cis-2-butene**: The two methyl (CH₃) groups are on the same side of the double bond.
- **Trans-2-butene**: The two methyl (CH₃) groups are on opposite sides of the double bond.

### Step 4: Draw the Structures
1. **Cis-2-butene**:
```
H
\
C=C
/ \
CH3 CH3
```

2. **Trans-2-butene**:
```
H CH3
\ /
C=C
/ \
CH3 H
```

### Step 5: Conclusion
Since 2-butene has two different groups on each carbon of the double bond, it can exhibit geometrical isomers. Therefore, 2-butene does show geometrical isomers, specifically cis-2-butene and trans-2-butene.

### Final Answer
Yes, 2-butene shows geometrical isomers (cis and trans).
