How is intermolecular forces related to boiling point? Intermolecular forces (IMFs) can be used to predict relative boiling points. The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point.
Do branched or linear structures have higher boiling points? Van Der Waal’s forces depend upon two major factors. A straight chain alkane will have a boiling point higher than a branched chain alkane because of the greater surface area in contact with other molecules. Branching makes molecules more compact thus reduces the surface area.
Why do symmetrical molecules have higher boiling points? By sticking together, the more symmetric molecules thus require more energy to energize them from the liquid state into the gaseous state. Polarity is the key in determining relative boiling point as it causes increased inter-molecular forces, thereby raising the boiling point.
Do linear molecules have higher melting points? Linear molecules will have more surface area than a more spherically shaped molecule. … Due to its long-thin shape, B will have a greater surface area and can form more dispersion interactions than the rounder C. Therefore, B will have a higher boiling point and melting point than C.
