Iodination of alkanes
WebIodination reactions that include iodolactonisation and iodoetherification represent a class of widely used alkene oxidation reactions. Several substrate-controlled … WebIodination is extremely slow and reversible in nature. HI is a strong reducing agent and converts methyl iodide back to methane. In order to carry out the reaction in the forward direction. HI is destroyed with the help of an oxidising agent like iodic acid (HIO3), concentrated. HNO3 or mercuric oxide (HgO).

WebAnswer (1 of 2): Fluorination of alkanes is highly exothermic which may explode. Iodination of alkanes is reversible reaction,as HI so produced is stronger reducing agent,it attacks on Alkyl iodides produced.Hence backward reaction is attributed. In order to prevent backward reaction, iodinatio... WebIodination of alkanes using iodine(I2) is usually an unfavorable reaction. (See Problem 4-17, for example.) Tetraiodomethane (CI4) can be used as the iodine sourcefor iodination, in the presence of a free-radical initiatorsuch as hydrogen peroxide.
