Final answer:
Water is the correct answer as it is a polar molecule with strong hydrogen bonding, making it a good solvent with adhesion and cohesion properties and a high boiling point.
Step-by-step explanation:
The molecule described in the question having the characteristics of being polar, having good solvent properties, having a high boiling point, and exhibiting both adhesion and cohesion is Water (H2O).
Water is known for its ability to form polar covalent bonds within its molecules and to attract other polar molecules forming hydrogen bonds. This makes water an excellent solvent, particularly for hydrophilic substances that are 'water-loving.' These properties, along with its high heat capacity, allow water to have a high boiling point of 100°C and strong intermolecular cohesion.
Other molecules mentioned such as Oxygen, Methane, and Carbon Dioxide do not possess the same combination of polar nature, high boiling point, and solvent abilities as water does. For example, Oxygen (O2) is a nonpolar molecule, Methane (CH4) has a much lower boiling point, and Carbon Dioxide (CO2) is not as effective a solvent for polar substances.
