2018年4月23日 · (i) Ethanol to 3-hydroxybutanal (ii) Benzaldehyde to Benzophenone. (b) An organic compound A has the molecular formula C 8 H 16 O 2. It gets hydrolysed with dilute sulphuric acid and gives a carboxylic acid B and an alcohol C. Oxidation of C with chromic acid also produced B. C on dehydration reaction gives but-1-ene.
How will you convert ethanal into the following compounds?
2) Ethanal into But$ - 2 - $enal: The first step will be aldol condensation reaction in presence of a base which will give $3 - $Hydroxybutanal. Then it will further undergo a dehydration reaction by giving heat which will give But$ - 2 - $enal as the product.

The conversion of ethanal to but-2-enal is carried out by aldol condensation reaction. Ethanol is acetaldehyde and contains an alpha hydrogen atom. In presence of dilute alkali, two molecules of ethanal condense to form 3-hydroxybutanal. Upon heating, this 3-hydroxybutanal loses a water molecule to form but-2-enal.

Ethanol when heated with copper produces an aldehyde, which then undergoes Aldol condensation to form 3-hydroxybutanal. During Aldol condensation, an alcohol with at least one α-H atom is converted into $\beta - $hydroxy aldehyde in presence of dilute alkali. The dilute alkali acts as a catalyst in Aldol condensation. 4.
