Steric collision is the physical interference that occurs when two molecules approach each other too closely due to their bulky groups or substituents. This results in repulsion between the electron clouds of the molecules, hindering proper binding or reaction. Steric effects play a crucial role in determining molecular shape, reactivity, and biological interactions.
Steric forces are the noncovalent interactions between atoms or groups that arise from the repulsion of electron clouds due to their proximity. These forces are important in determining molecular shape, affecting molecular conformation, and influencing the stability of chemical compounds. Steric hindrance is a common consequence of these forces, which can impact the reactivity and behavior of molecules.
The adjective form for the noun collision is collisional.
An elastic collision conserves kinetic energy. In this type of collision, the total kinetic energy before the collision is equal to the total kinetic energy after the collision.
Collision.
In an elastic collision, both kinetic energy and momentum are conserved. This means that the total kinetic energy before the collision is equal to the total kinetic energy after the collision, and the total momentum before the collision is equal to the total momentum after the collision.
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.
To determine the orbital hybridization of an atom in a molecule, you can look at the atom's steric number, which is the sum of the number of bonded atoms and lone pairs around the atom. The hybridization is determined by the steric number according to the following guidelines: Steric number 2: sp hybridization Steric number 3: sp2 hybridization Steric number 4: sp3 hybridization Steric number 5: sp3d hybridization Steric number 6: sp3d2 hybridization By identifying the steric number, you can determine the orbital hybridization of the atom in the molecule.
The structures and properties can be used to describe the relation between a steric hindrance and reactivity.
The steric number of carbon disulfide is 2. This is because carbon has two bonded atoms (sulfur), and there are no lone pairs around the central carbon atom. The steric number is determined by the sum of bonded atoms and lone pairs around the central atom.
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.

The steric number of NO2 is 3, which is calculated by adding the number of atoms directly bonded to the central atom (N) and the number of lone pairs on the central atom. In this case, the nitrogen (N) atom is directly bonded to 2 oxygen (O) atoms and has 1 lone pair, giving a steric number of 3.

Steric interference refers to the hindrance in the free rotation of functional groups or atoms in a molecule due to their close proximity. This can lead to unfavorable interactions or prevent certain reactions from occurring. Steric hindrance can affect the reactivity, stability, or conformation of a molecule.
A hindered nucleophile is a nucleophile that has steric hindrance around the nucleophilic center, making it less reactive due to difficulty in approaching the electrophilic site. This steric hindrance can result from bulky substituents nearby the nucleophilic atom.
