    By the cause of branching the chain makes the molecule more compact, weakens the crystal lattice structure of the compound and thus drops the surface area. Hence, spreading forces reduces as there are fewer places for interaction, so decreasing the amount of energy required to break the intermolecular forces of attraction. 2-hexanone has the lowest point boiling point, as it much more branched and the third carbon has a functional group (double bond O), leading a high compacted molecule. Pentanol and hexanol molecules has the least amount of branching out of the four compounds above in the graph, and as such has the highest boiling…

    with low vapor pressure. Vapor pressure of an alcohol is affected by many things, including boiling point. Vapor pressure and boiling point are directly related, so if the boiling point is increased, the vapor pressure is increased. Also molar mass affects vapor pressure. Molar mass and vapor pressure have an indirect relationship, so the lower the molar mass, the higher the vapor pressure. However, as the molar mass of any substance, like alkanes and carboxylic acids, increases the vapor…

    boiling point increase when the addition of an extra carbon atom in a straight-chain homologous series of saturated alcohols occurs?” On average, as per calculations conducted, the boiling point increases by a magnitude of approximately 14.1 ℃. Granted such quantitative evidence, in addition to its corresponding visual plotting detailed in figure 2.1, it could reasonably be determined that a quite linear correlation indeed exists between carbon-chain length and boiling point. This is highly…
