I think torsional strain happens only when two groups are eclipsed in relation to their positions to each other. This strain can be relieved by rotation about the carbon carbon bond. But steric strain can happen all the time. (when two groups are eclipsed, gauge or staggered in relation to each other.)
Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.
By the changing the angles of forces, the system of the forces will be in equilibrium.

Due to the steric crowding the tetrahedral inter-mediate can't be form and thus esterification can't take place;this is called steric retardation.
The structures and properties can be used to describe the relation between a steric hindrance and reactivity.

For Sn1 reaction the rate usually increases due to steric acceleration. For example the more methyl groups a compound has i.e the more tertiary it is the faster the rate of reaction will be for an Sn1 reaction.
chair form as the steric repulsions is minimum
because it bubbles upbecause it changes colour
pharmacophore
Van der Waals strain is one example

The react to form zinc sterate and water
When an atom comes too close to another atom, their electron clouds overlap and repel, this state is unfavorable and is characterized by higher energy.
