Question

7. Intimate ion pair is formed in the following mechanism.
a) SN1
b) SN2
c) SNi
d) SNAr​

Answer 1

In chemistry the intimate ion pair concept introduced by Saul Winstein describes the interactions between a cation, anion and surrounding solvent molecules.[1] In ordinary aqueous solutions of inorganic salts an ion is completely solvated and shielded from the counterion. In less polar solvents two ions can still be connected to some extent. In a tight or intimate or contact ion pair there are no solvent molecules between the two ions. When solvation increases, ionic bonding decreases and a loose or solvent-shared ion pair results. The ion pair concept explains stereochemistry in solvolysis.

Answer 2

Answer:

option (A) SN1

Explanation:

the concept of intimate ion pairs is used to explain the slight tendency for inversion of stereochemistry during an SN1 reaction
