Straight chain isomers have higher boiling point than their more compact isomers because there are fewer dispersion forces in the symmetrical molecule
The dispersion forces of straight chain alkanes increase with molecular weight.
Stronger intermolecular forces develop in long chains, and the boiling point and melting point increase with MW.

What are the differences between n-butane and isobutane in terms of their properties and applications?
N-butane and isobutane are both hydrocarbons, but they have different structures and properties. N-butane has a straight chain structure, while isobutane has a branched structure. Isobutane has a lower boiling point and is more stable than n-butane. In terms of applications, n-butane is commonly used as a fuel for lighters and camping stoves, while isobutane is often used as a refrigerant in air conditioning systems.
What are the differences between isobutane and n-butane in terms of their properties and applications?
Isobutane and n-butane are both hydrocarbon gases, but they differ in their molecular structures. Isobutane has a branched structure, while n-butane has a straight chain structure. This difference affects their properties and applications. Isobutane has a higher vapor pressure and is more volatile than n-butane. It is commonly used as a refrigerant and in aerosol propellants. N-butane is often used as a fuel for portable stoves and lighters due to its lower vapor pressure and higher boiling point.
How do polarity and shape of molecules relate to the properties of a substance?
Polarity and shape affect the ability of molecules to aggregate and pack together. Higher polarity, for example, may allow for hydrogen bonding to occur in certain instances which greatly increases a substance's melting and boiling points. If you compare CO2, which is non-polar and a gas at room temperature, to water (H2O) which is polar and is a liquid at room temperature, the different is due to polarity and hydrogen bonding. A good example of the effect of molecular shape on physical properties of compound is a comparison between isobutane and n-butane. Isobutane has a boiling point of -11.7 degrees C whereas n-butane boils roughly around 0 degrees C. Why does n-butane have a higher boiling point? Because n-butane is a straight-chain hydrocarbon which can pack well with other n-butane molecules around it. This maximizes molecular interaction and the weak intermolecular forces (i.e. London/van der Walls) keeping the molecules together. Isobutane, meanwhile, has less contact with other isobutane molecules because of its 3D shape/geometry which is more rigid than that of n-butane.
What does the n stand for in n-butane?
The "n" in n-butane stands for "normal," indicating that the carbon atoms are arranged in a straight, or normal, chain.
What are the two structural forms of butane?
The two structural forms of butane are n-butane (normal butane) and iso-butane (isobutane). n-Butane has a straight-chain structure with four carbon atoms in a row, while iso-butane has a branched structure with a central carbon atom bonded to three other carbon atoms.
What is the freezing point of butane?
n-butane : Melting point −138.4 °C (135.4 K), boiling at −0.5 °C (272.6 K)iso-butane (methylpropane): Melting point -159.6 °C, (114 K) , boiling at -11.7 °C, (261 K)
