To determine which of the given compounds will not show geometrical isomerism, we need to analyze each option based on the criteria for geometrical isomerism. This type of isomerism occurs in compounds with a carbon-carbon double bond (C=C) when the groups attached to the carbons are different.
### Step-by-Step Solution:
1. **Understand the Criteria for Geometrical Isomerism**:
- Geometrical isomerism (also known as cis-trans isomerism) occurs when there is a carbon-carbon double bond (C=C) and the two groups attached to each carbon are different.
- If the groups attached to the double-bonded carbons are the same, geometrical isomerism cannot occur.
2. **Analyze Each Option**:
- **Option 1**: C=C with groups H, CS2, CS3, CS3
- Here, one carbon is attached to two identical groups (CS3). Since both groups are the same, this compound will **not** show geometrical isomerism.
- **Option 2**: C=C with groups H, CS2, CS3, CH, CS3, CS3
- In this case, all groups attached to the double bond are different, so this compound **will** show geometrical isomerism.
- **Option 3**: C=C with groups CS3, CS3
- Similar to option 1, both groups are identical (CS3), so this compound will **not** show geometrical isomerism.
- **Option 4**: C=C with groups CS2, CS3, CS3
- Here, both groups are different, so this compound **will** show geometrical isomerism.
3. **Conclusion**:
- From the analysis, we can conclude that **Option 1** does not show geometrical isomerism because it has two identical groups attached to the double bond.
### Final Answer:
**Option 1 will not show geometrical isomerism.**
