Question

ethyl iodide become Violet on standing in presence of light​

Answer 1

Answer:

Ethyl iodide becomes violet on standing in the presence of light​ because it decomposes to form iodine.

Alkyl iodides are the least stable compared to alkyl fluorides, chlorides or bromides and because of this the C-X bond breaks down easily thereby liberating iodine.

The reaction is given as follows:

2R-I ------------------> R-R + I2
