finkelstein reaction meaning in Hindi

Examples

1. Chloro-and bromoalkanes are readily substituted by iodide in the Finkelstein reaction.
2. Alkyl halides differ greatly in the ease with which they undergo the Finkelstein reaction.
3. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.
4. The iodide anion is a good nucleophile and will displace chloride, tosylate, bromide and other leaving groups, as in the Finkelstein reaction.
5. Halogen exchange to produce iodoalkanes by the Finkelstein reaction is slightly complicated by the fact that iodide is a better leaving group than chloride or bromide.
6. The classic Finkelstein reaction entails the conversion of an alkyl chloride or an alkyl bromide to an alkyl iodide by treatment with a solution of sodium iodide in acetone.
7. Allyl iodide can be synthesized from methyl iodide on triphenyl phosphite, Finkelstein reaction on allyl halides, or by the action of elemental phosphorus and iodine on glycerol.
8. If I produce diiodomethane using the Finkelstein reaction by dissolving DCM and sodium iodide in acetone, the problem is that even if I evaporate the acetone and any leftover DCM ( leaving just the diiodomethane ) I think the acetone will form an azeotrope with the diiodomethane, and this acetone will act as a surfactant and interfere with acid-base extraction during workup . ( The octanol / water logP is-0.042, or an octanol / water partition coefficient of 0.9 ).
