Heptane is a simple organic molecule, it has the structure CH3-CH2-CH2-CH2-CH2-CH2-CH3. Although it does not have linear bond angles, the molecule is loosely stick-shaped overall in its most stable form. This means that most of the heptane is able to touch other heptane molecules (imagine a bunch of pens in a cup, or a plate of cooked spaghetti). This, and the length of the molecule allow for intermolecular attractive forces of a magnitude large enough that the substance is liquid at room temperature. These forces are called non-polar interactions, or London dispersion forces. Although this molecule has no charges or polar groups, it the temporary forces caused by the intermolecular interactions are strong enough to liquefy it. These forces get stronger as the molecule gets bigger. That is why methane (only one carbon atom long) is a gas at room temperature and heptane is a liquid. Longer hydrocarbons have such strong interactions that they become waxes. The forces get weaker when the carbons are attached to each other in any way other than a straight line. Search wikipedia for pentane, a 5 carbon hydrocarbon that is in a straight line and is a liquid at room temperature. And search wikipedia for neopentane, a 5 carbon hydrocarbon that is not in a straight line and is a gas at room temperature.
