Iodine does not react with ethane though I2 is more easily cleaved hom

1.	Iodine does not react with ethane though I2 is more easily cleaved homolytically than the other halogens. Explain.
Answer» Bond dissociation enthalfy of I₂ is less as compared to that of Cl₂ and Br₂ which means that the homolysis of I₂ is the easier. However , HI formed in a reaction is a strong reducing agent and it makes the reaction reversible. Therfore, iodine does not reacts reversible. Therfore, iodine does not reacts with ethane. CH₃ – CH₃ +I₂ -------------> CH₃ – CH₂ – I + HI Ethane Iodoethane
