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.
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 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 strain in organic chemistry refers to the repulsion between atoms or groups of atoms that are too close together. This strain can affect the conformation of molecules by causing them to adopt certain shapes or conformations that minimize this repulsion. In other words, steric strain influences the spatial arrangement of atoms in a molecule, leading to specific shapes and structures.
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.
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.

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 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.

Van der Waals strain is one example
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.
