So, why should we care about torsional strain? Well, it plays a big role in determining the stability and reactivity of molecules. Imagine you're a chemist trying to create a new medicine - you need to understand how the molecules will behave and interact with each other. And, torsional strain is a key factor in all of this.
For example, some molecules might be more reactive because they have a lot of torsional strain, making them more likely to break or change shape. It's like a coiled spring - the more energy that's stored, the more likely it is to release that energy and do something interesting.
