Web10 mrt. 2024 · Molecular weight is a critical factor that affects the melting point of PLA. As the molecular weight of PLA increases, its melting point also increases. This is because high molecular weight polymers have more entanglements and intermolecular interactions, which require more energy to break the bonds and transition from a solid to a liquid state. WebGiven this information regarding polarity and the molecular weights of the compound, it is easy to conclude that the weight of the tetracosane caused it to have a higher melting point. Conclusion At the conclusion of this experiment, I have a better understanding of the significance of organic compound’s physical properties.
