Iodethylene: The Forgotten Haloalkene

Iodethylene, with the chemical formula CI2H4I, is a haloalkene that has often been overlooked in the realm of chemistry. Despite its relative obscurity, it holds great significance in the study of organic chemistry and offers valuable insights into the reactivity of haloalkenes. In this article, we will delve into the fascinating world of iodethylene, exploring its preparation, properties, and applications.

Preparation of Iodethylene

Iodethylene can be synthesized through a variety of methods, but the most common route involves the dehydration of ethylene iodide (CI2H5I) using an acidic catalyst such as concentrated sulfuric acid (H2SO4). The reaction proceeds as follows:

CI2H5I H2SO4 → CI2H4I H2O

This method is preferred due to its simplicity and the ease of handling the reactants and products. However, it is important to handle ethylene iodide and concentrated sulfuric acid with care, as they are hazardous substances.

Reactivity of Iodethylene

Iodethylene, like other haloalkenes, exhibits unique reactivity due to the presence of the halogen atom. The electronegativity of iodine (I) is higher than that of carbon (C) and hydrogen (H), resulting in a polar carbon
