### Boiling Point Comparison of Molecules

#### Question:
Which of the two molecules shown below would have the higher boiling point?

#### Molecule Structures:
- **Molecule A:** 
  - Structure: Cl—C=C—Cl
  - Other atoms: H bonded to both Carbons

- **Molecule B:** 
  - Structure: Cl—C=C—Cl
  - Other atoms: H bonded to only one Carbon and H bonded to the other, forming a symmetrical structure.

#### Choices:
1. A
2. Same boiling point for each
3. B

In this exercise, students are asked to determine which of the given molecules (A or B) would have a higher boiling point. By considering intermolecular forces and molecular symmetry, they can deduce that molecule A, having two chlorine atoms bonded to carbon atoms in a symmetrical fashion, is likely to have stronger intermolecular forces due to dipole interactions compared to molecule B. These concepts are crucial for understanding physical properties of compounds in chemistry.

This problem encourages learners to apply knowledge of molecular structure and intermolecular forces to predict boiling points, a foundational topic in chemistry education.
