Dispersion interactions, also known as London dispersion forces, are weak intermolecular attractions that occur in all molecules, including nonpolar ones. These forces result from temporary fluctuations in the electron distribution within molecules, which induce corresponding temporary dipoles in neighboring molecules. Therefore, regardless of the specific compounds listed in the query, all compounds exhibit dispersion interactions to some extent. The strength of these interactions increases with the molar mass and size of the molecule because larger molecules have more electrons, which can lead to larger temporary dipoles. Hence, these interactions are universal but vary in strength from one compound to another based on molecular size and shape.

Ink spreading on a phone screen, often mistaken for actual ink, is typically due to a liquid crystal display (LCD) leak, which occurs when the screen is cracked or damaged. To prevent further spreading, immediate action is required. Turn off the device and avoid pressing the affected area to prevent the liquid crystals from spreading further. Do not attempt to fix it yourself as it could cause more harm. The best course of action is to take it to a professional repair service as soon as possible. They can assess the damage and replace the screen if necessary. Preventative measures include using a screen protector and a sturdy case to protect against future accidents.
