Verified step by step guidance

Understand that dispersion forces, also known as London dispersion forces, are a type of van der Waals force that occur between molecules due to temporary dipoles created by electron movement.

Recognize that dispersion forces increase with the size of the molecule, specifically the number of electrons and the surface area available for interactions.

Compare the molecular structures of the given species: CH4 (methane), CH3CH3 (ethane), CH3CH2CH3 (propane), and C12H26 (dodecane).

Note that C12H26 has the largest number of carbon atoms and hydrogen atoms, resulting in the highest number of electrons and the largest surface area among the given species.

Conclude that C12H26 is expected to have the largest dispersion forces due to its larger size and greater electron cloud compared to the other molecules listed.
