Why do polar solvent and weak nucleophiles favor SN1 reaction?

Polar protic solvents, such as CH3OH, CH3CH2-OH, H2O, etc., are suitable for SN1 reactions. This is because in this type of solvent, both carbocation and halide anion gain stability. That is, polar protic solvent favor SN1 reaction mechanism. The strength of nucleophile depends on the electronegativity of the concern attacking…

Why do stronger nucleophiles favor SN2 reaction mechanism?

A stronger nucleophile is a highly electron rich or fully negative charge species. It has been experimentally found that the stronger nucleophile favor SN2 reaction mechanism. They have a tendency to react with carbocation more quickly, before a leaving group would have a chance to dissociate and proceed through an…

Why do nucleophiles always attack from backside in SN2 reactions?

The SN2 reaction occurs in one step through the backside attack. That is, in this reaction, the nucleophile attacks the carbon atom of the substrate from the opposite side of the living group. The SN2 reaction is completed through the formation of a transition state. In the transition state, the…

What is catenation property of carbon?

Catenation property is found in organic as well as in inorganic compounds. The catenation property mainly shows carbon element in organic chemistry. When two or more atoms of an element combine with each other through the covalently single bond, double bond or triple bond to form a long chain structure…

What is chiral center or stereogenic center?

Optical isomerism: The isomerism in which two or more compounds have same physical and chemical properties but they have different behavior towards plane polarized light, are known as optical isomerism and such type of compounds are known as optically active compounds. Chiral centers: When a single tetrahedral atom is attached with four…
