Question

Compound which when reacts with water forms ethyne

Answer 1

Alkynes readily combine with water in the presence of acid (usually sulfuric acid) and mercury(II) salts (usually the sulfate is used) to form carbonyl compounds, in a process known as Kucherov's reaction. In the case of acetylene (ethyne) the product isacetaldehyde (ethanal), while other alkynes form ketones.
