Answer:
Explanation:
Many elements have similar properties. This can be seen in how periodic table is arranged. The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.
For eg: Lithium, Sodium, and Potassium fall under group one in periodic table. These elements exhibit similar properties such as being extremely reactive.

Answer:
London dispersion forces
Explanation:
Intermolecular forces are the forces that facilitate interaction between solute and solvent molecules and thereby impact their solubility. These forces are broadly classified into four types arranged below from the strongest to the weakest:
1) Ionic > 2) Hydrogen bonding >3) Dipole-dipole >4) London dispersion
The hydrocarbons n-pentane 
and n--hexane 
are non-polar molecules. Therefore the only type of interaction that exists between them when forming a homogeneous solution are the weak london dispersion forces.
This one was too easy it's CCl4
