Sodium iodide is an iodide salt that can be used as an injectable medicinal drug. If we compare the transition state for cyclobromopropane 2-bromopropane then we see in case of cyclobromopropane transition state, one of the H is very close to the incoming I -. The mechanism is largely S N 2, so primary alkyl halides react faster than secondary alkyl halides, and tertiary alkyl halides generally give no reaction. Sodium iodide is an iodide salt that can be used as an injectable medicinal drug. The average rate constant for this reaction was 29.9 x 10⁻⁴ moles⁻¹ litre sec⁻¹ at 50.1°C. The first page of this article is displayed as the abstract. Talk with the doctor. 1954;287(9-10):561-5. In tests with sodium iodide in acetone and silver nitrate in ethanol, why should 2-bromobutane react faster than - Answered by a verified Tutor. Sodium bromide is used in conjunction with chlorine as a disinfectant for hot tubs and swimming pools. Iodine is liberated from iodate and iodide according to the equation: IO 3-+ 5I-+ 6H + → 3I 2 + 3H 2O The iodine solution, which is a golden-brown colour, can be titrated against sodium thiosulfate solution. c) Would 1-iodobutane react faster or slower than the other halides?

After five minutes, the test tubes which had no precipitate yet formed were placed in a 50˚C water bath. 1)In the test with sodium iodide in acetone and silver nitrate in ethanol, why should 2-bromobutane react faster than 2-chlorobutane? These insoluble salts may precipitate from the reaction mixture, indicating that the SN 2 reaction occurred. Add 2 drops of 1-bromobutane (butyl bromide) to the first test tube; add 2 drops of 2-bromobutane (sec-butyl bromide) to the second test tube; and add 2 drops of 2-methyl-2-bromopropane (t-butyl bromide) to the third test tube. It's very useful for metathesis reactions with other halides, because sodium chloride and bromide are far less soluble, and precipitate nicely from dry acetone. SODIUM IODIDE IN ACETONE (for alkyl halides that can undergo Sn2 reactions) – Primary and some secondary alkyl chlorides or bromides will give a precipitate of sodium iodide in the reagent.
