Question

an organic compound gives H2 gas wiyh sodium metal. on treatment with alkaline iodide give yellow ppt on oxidation with CeO2/ H+ formed an aldeyde . name the compound and write reaction involve. how would you convert the compound into ethene?

Answer 1

Answer:

This is chemically the more obvious method. Iodine solution is added to a small amount of aldehyde or ketone, followed by just enough sodium hydroxide solution to remove the color of the iodine. If nothing happens in the cold, it may be necessary to warm the mixture very gently. A positive result is the appearance of a very pale yellow precipitate of triiodomethane (previously known as iodoform) - CHI3. Apart from its color, this can be recognised by its faintly "medical" smell. It is used as an antiseptic on the sort of sticky plasters you put on minor cuts, for example.
