Torsional strain and steric hindrance both affect the shape and reactivity of molecules, but in different ways. Torsional strain is caused by the resistance to rotation around a bond, leading to a twisted conformation. This strain can affect the stability and reactivity of a molecule. On the other hand, steric hindrance is caused by bulky groups that physically block the movement of other groups, affecting the shape and reactivity of the molecule. In summary, torsional strain is due to bond rotation, while steric hindrance is due to bulky groups blocking movement.
Torsional strain is caused by the resistance to rotation around a bond, leading to higher energy and less stability in a molecule's conformation. Steric strain is caused by repulsion between bulky groups, also resulting in higher energy and less stability. Both strains affect molecular conformation and stability by distorting the molecule's shape and increasing its energy.
Torsional strain occurs when atoms in a molecule are forced to adopt unfavorable positions due to repulsion between electron clouds. This strain can destabilize the molecule's conformation by increasing its energy. In turn, this can lead to a less stable and less favorable molecular structure.
Steric strain is caused by repulsion between atoms or groups that are too close together, leading to distortion of the molecule's shape. Torsional strain, on the other hand, is caused by resistance to rotation around a bond, which can also distort the molecule's shape. Both types of strain can affect molecular conformation and stability by increasing energy levels and making the molecule less stable.
Torsional strain is caused by the repulsion between atoms in a molecule due to their bond angles, while steric strain is caused by the repulsion between bulky groups on adjacent atoms. Torsional strain affects the rotation of bonds in a molecule, while steric strain affects the overall shape and stability of the molecule. Both strains can impact the conformation and stability of a molecule, but in different ways.
I beg to differ :) .Its the opposite, Staggered conformations are more stable than eclipsed conformations. This is due to the presence of less Steric effect in the staggered conformation than the eclipsed forms.

Skew confirmation in Newman projection refers to a specific arrangement of atoms or groups around a carbon-carbon bond, where the substituents are positioned at an angle to one another rather than directly eclipsing. This conformation minimizes steric strain compared to the eclipsed conformation, resulting in lower energy and greater stability. The skewed arrangement allows for some degree of torsional strain reduction, making it a favorable conformation in many molecular structures. It is often depicted by rotating the front and back carbon atoms to achieve this staggered-like perspective.
The staggered confirmation of ethane is more stable because it has lower torsional strain, resulting from the eclipsing of carbon-hydrogen bonds in the eclipsed conformation. In the staggered conformation, the carbon-hydrogen bonds are as far apart as possible, minimizing repulsive interactions. This results in lower energy and higher stability compared to the eclipsed conformation.
Torsional strain is the resistance to twisting in a molecule's structure, caused by the repulsion between atoms or groups that are forced too close together. This strain can lead to instability in molecules, affecting their overall stability and potentially influencing their reactivity and properties.
Torsional analysis: This analysis completed based on strcture properties like Mass MI and Torsional stiffness. Torsional critical speed analysis: Speed of rotor will come into picture in addition to Mass MI and Torsional stiffness of the structure.
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.)
It is defined as ratio of the product of modulus of rigidity and polar moment of inertia to the length of the shaft. Torsional Rigidity is caluclated as: Torsional Rigidity= C J/l
The term torsional critical speed of centrifugal pumps and associated drive equipment refers to the speed of a pump rotor or related rotating system that corresponds to a resonant frequency of torsional vibration of the rotating system. Torsional critical speeds are associated with torsional or angular deflection of the rotor and are not to be confused with lateral critical speeds associated with lateral deflection. The two are separate entities. A given rotor or rotating system may possess more than one torsional resonant frequency or torsional critical speed. The lowest frequency which produces the "first mode shape" and "first torsional critical speed" is in general of the most concern. Torsional vibration is caused by torsional excitation from sources such as variable frequency drive motor toque pulsations, combustion engine torque spikes and impeller vane pass pulsation. The calculation of the first torsional critical speed is fairly simple for simple rotor systems.
