Why is acetone used with NaI?

In this reaction, ethyl chloride (a primary alkyl halide) is treated with sodium iodide (the nucleophile) to produce ethyl iodide. Acetone is used as the solvent because NaI (being polar) is soluble in acetone (non-polar) while NaCl is not soluble.

Why do we use acetone in Finkelstein reaction?

Acetone is a widely used organic solvent thus in anhydrous condition i.e. when acetone is pure which having water, its used in Finkelstein’s reaction to facilitates the forward reaction according to Le Chatelier’s Principle.

Why is NaI more soluble in acetone?

This larger distance between the ions decreases the lattice energy, which in turn makes the compound readily soluble in acetone.

Does acetone dissolve NaI?

Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not. The reaction is driven toward products by mass action due to the precipitation of the poorly soluble NaCl or NaBr.

What does NaI do?

Sodium iodide activated with thallium, NaI(Tl), when subjected to ionizing radiation, emits photons (i.e., scintillate) and is used in scintillation detectors, traditionally in nuclear medicine, geophysics, nuclear physics, and environmental measurements. NaI(Tl) is the most widely used scintillation material.

What is the use of acetone in reaction?

Chemical research In the laboratory, acetone is used as a polar, aprotic solvent in a variety of organic reactions, such as SN2 reactions. The use of acetone solvent is critical for the Jones oxidation.

What is the role of dry acetone?

Dry acetone is used for purifying water sensitive compounds or for very water sensitive reactions. It can be prepared in multiple ways but if not done properly it may lead to auto-condensation or formation of peroxides that are explosive.

Why is NaI more soluble in acetone than NaCl?

This may bring about some covalent character to the interaction between Na+ and I-. This makes NaI soluble in less polar solvents like acetone, methanol, ethanol, etc., but NaCl and NaBr are not so.

Why is acetone used in SN1?

The SN1 Tends To Proceed In Polar Protic Solvents. The SN2 reaction is favored by polar aprotic solvents – these are solvents such as acetone, DMSO, acetonitrile, or DMF that are polar enough to dissolve the substrate and nucleophile but do not participate in hydrogen bonding with the nucleophile.
