I’m working on a chemistry discussion question and need an explanation to help me study.
Intermolecular forces play fundamental roles that affect substances’ properties including:
- Vapor pressure
- Capillary action
- Boiling point/Melting point
Examine a specific case that interests you where intermolecular forces play an important role. Some ideas include:
- Solubility: Like-dissolves-like
- Why are some vitamins like vitamin A toxic at high concentrations, but others like vitamin C are not?
- How do soaps and alcohols act as antimicrobials?
- How do soaps make grease become soluble?
- Capillary Action
- How do plants use capillary action to move water into their stems and leaves?
- Hydrogen bonding
- How do hydrogen bonds play a role in DNA structure?
- How do hydrogen bonds play a role in drugs binding to their targets. (You can return to your previous discussion on molecular shapes and examine drug-target binding. The molecular modeling program that you used draws dashed lines to represent hydrogen bonds between the drug and its target).
- Boiling point/melting point
- How do London-dispersion forces affect melting points of triglycerides, causing some to be fats while others are oils.
- What is the difference between old-fashioned peanut butter and hydrogenated peanut butter and why is hydrogenated peanut butter solid at room temperature?
- Consider the intermolecular forces that must occur when a virus infects a cell. Here’s a video simulation. This might require some advance knowledge of biology, but still, you can see there are a lot of interactions that must occur.
