![## Surface Tension Comparison of Organic Compounds
### Question
**I. Select the compound with the greater surface tension:**
### Provided Data
Two compounds labeled A and B are given in the following table:
| **A** | **B** |
|:---------:|:---------:|
| CH₃CH₂CH₂CH₂NH₂ | CH₃CH₂CH₂CH₂CH₃ |
### Task
Using the provided data, select the compound with the greater surface tension.
**[ Select ]**
**Note:**
- Compound A: CH₃CH₂CH₂CH₂NH₂
- Compound B: CH₃CH₂CH₂CH₂CH₃
### Explanation
Surface tension is a molecular phenomenon caused by cohesive forces among molecules. Compounds with polar chemical groups typically exhibit higher surface tension due to these cohesive forces.
- Compound A, containing an amine group (NH₂), is expected to have higher surface tension compared to Compound B, which is a non-polar hydrocarbon chain.
#### Selection Option
Determine which compound (A or B) has the greater surface tension from the choices provided.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdc325aa0-3b4d-4100-824a-15814ab6662e%2Fd7f51447-a7b1-42d2-b937-427911f10e8b%2Ffc670ml_processed.jpeg&w=3840&q=75)
