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.
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.
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.
Pseudo-retardation would be something that resembles or looks like retardation, but actually isn't. The term literally means, fake retardation.
No a dimple is not a sign of retardation.
Retardation = change in vel / time taken
Retardation - 2015 was released on: USA: 2015
Overstudy does not cause mental retardation.
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 first spelling is correct: "Retardation."
Mental retardation has different levels. There is Mild intellectual disability; moderate intellectual disability; severe intellectual disability; and Profound intellectual disability.https://www.floridahospital.com/mental-retardation-mr/symptoms-and-signs-mental-retardation
