WebEthanol can be dehydrated to give ethene by heating it with an excess of concentrated sulphuric acid at 170 0C. The acid catalysts normally used in alcohol dehydration is concentrated sulphuric acid which results in alkene. C 2H 5OH+conc.H 2SO 4→C 2H 4+H 2O. Was this answer helpful? WebCorrect option is C) When an alkyne is reacted with aqueous H 2SO 4 in presence of HgSO 4, it is converted to a ketone. But ethyne is an exception. It gives acetaldehyde in this reaction. Propyne in the reaction is converted to acetone (propanone). Solve any question of The p-Block Elements with:-. Patterns of problems. ai引擎托管平台

WebThe hydration of alkynes gives ketones (except in the case of acetylene itself, which gives an aldehyde; see Study Problem 14.1, p. 656). Let’s contrast the hydration reactions of alkenes (Sec. 4.9B) and alkynes. The hydration of an alkene gives an alcohol. Because addition reactions of alkenes and alkynes are closely analogous, it might seem ... WebOnly ethyne is possible to convert to aldehyde (ethanal) from hyrolysis. What are the products of hydration of ethene. Ethanol is only product of hydration of ethene. Dilute H … Web1 Answers. When ethyne is treated with H2SO4 in presence of HgSO4, then addition of water to ethyne takes place. This reaction is generally known as hydration reaction. The water molecule under the mentioned conditions add to the tripple bond in order to form an enol intermediate. This intermediates is shot lived which readily undergoes ... ai弧形文字怎么反过来
