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.

What are steric forces?
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.
What is adjective for collision?
The adjective form for the noun collision is collisional.
What type of collision is kinetic energy is conserved?
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.
What Abstract noun of collide?
Collision.
What does elastic collision mean?
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.
What is steric retardation?
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.
How can one determine the orbital hybridization of an atom in a molecule?
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.
What is the relation between steric hindrance and reactivity?
The structures and properties can be used to describe the relation between a steric hindrance and reactivity.
What is the steric number of carbon disulfide?
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.
What is steric acceleration?
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.

When a collision occurs between two reactant particles that between them have the required minimum kinetic energy or activation energy a product does not always form. what reasons ex?
Even when reactant particles collide with sufficient kinetic energy, a product may not form due to factors such as improper orientation during the collision, which prevents the necessary bonds from breaking and forming. Additionally, the presence of competing reactions or steric hindrance can inhibit product formation. Finally, some reactions may require specific conditions, such as temperature or pressure, that are not met despite the collision occurring.
What is the steric number of NO2?
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.
What is steric interference?
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.
What is the IUPAC term for an ensemble of steric and electronic features that is essential to an interaction?
pharmacophore
What are the types of steric strain?
Van der Waals strain is one example
What is a hindered nucleophile?
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.
