Question

what happen when cis 1,2 dibromo cyclohexane heated with iodide ion​

Answer 1

Answer:

I predicted that the product would be 1,2-diiodo-4-methylcyclohexane because I thought the reaction conditions favoured substition with iodide via the SN2 mechanism. Firstly, iodide is a rather good nucleophile and secondly, the substrate is a secondary alkyl halide. Even if it was not SN2, I would expect perhaps SN1 since iodide is a rather weak base and the conditions do not seem to favour elimination
