What is the structure of NaI?
NaISodium iodide / Formula
Is NaI soluble acetone?
1. Iodide ion is a good nucleophile and sodium iodide is quite soluble in acetone. On the other hand, sodium chloride and sodium bromide have low solubilities in acetone. As a result, the reaction of alkyl bromides and alkyl chlorides with NaI/acetone can serve as a simple test reaction as indicated below.
Which compound on reaction is NaI acetone?
meso-2,3-dibromobutane on reaction with NaI/acetone gives trans-2-butene.
What type of compound is NaI?
ionic compound
Sodium iodide is a metal iodide salt with a Na(+) counterion. It is an inorganic sodium salt and an iodide salt. Sodium iodide is a water-soluble ionic compound with a crystal lattice.
Why is NaI soluble in acetone?
Here, Iodine anion is larger in size(ionic radius) than chlorine or bromine anion. This makes NaI attain some covalent properties. Therefore, it easily dissolves with dry acetone( which is an organic solvent and covalent character allows compunds to be soluble in Organic solvents).
What is the name of ca2c?
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide.
Why NaI is used in Finkelstein?
Finkelstein reaction is used to prepare alkyl iodides starting from alkyl chlorides and alkyl bromides. In this reaction alkyl chlorides or bromides are treated with NaI in presence of acetone to form alkyl iodides. In acetone, NaI is soluble ,as its lattice energy is lesser than the solvation energy of acetone.
Why is NaI soluble?
NaI is an ionic compound which can dissolve in water due to the polar nature of water molecules. [example here]. Iodine is made up of molecules of I2, which individually have no dipole moment (I-I bond has no dipole as both iodine atoms have same electronegativity).
Why is SN2 favored by NaI in acetone?
For SN2 reactions, NaI in acetone is chosen as iodide ion is a good nucleophile and acetone is a polar aprotic solvent, favoring a SN2 mechanism. The NaBr and NaCl formed in this reaction are insoluble in acetone, so that the time to produce a cloudy solution can be compared as a measure of relative rates.
Why is sodium iodide used in Finkelstein reaction?
The preparation of alkyl iodide from alkyl bromide or chloride with potassium or sodium iodide in acetone is generally known as the Finkelstein reaction. This reaction is a simple nucleophilic substitution (often via SN2) and iodide is found to be stronger nucleophile than bromide or chloride.
Does NaI dissociate in acetone?
The advantage of using Acetone for this reaction is that all hallides of Na+ exept NaI are insoluble in acetone. As NaI is our reactant, dissolution of it in Acetone will increase rate of reaction to right hand side and will leaad to formation of products faster.
What is the mechanism of NAI in acetone with alkyl halide?
What is the mechanism of the reaction of NaI in acetone with an alkyl halide? This operates by the SN 2 mechanism. The iodide ion is a reasonably good nucleophile, and adds as I − Because sodium iodide is much more soluble than sodium chloride in acetone, when you do this you see a glassy precipitate of sodium chloride in the acetone.
What is the chemical name of the compound Nai?
From Wikipedia, the free encyclopedia Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na +) and iodide anions (I −) in a crystal lattice.
Is Nai ionic or covalent?
?) Sodium iodide ( chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a white, water-soluble solid comprising a 1:1 mix of sodium cations (Na +) and iodide anions (I −) in a crystal lattice.
