Hydroxylation of ethyne

Vedclass · Answer

(A) $1$. Hydroxylation of ethyne $(C_2H_2)$ typically yields glyoxal or oxalic acid,not an alkene.$2$. $C_2H_5OH \xrightarrow{HI/red, P, 150 ^\circ C}$ produces ethane $(C_2H_6)$,an alkane.$3$. Butanone $\xrightarrow{Zn/Hg, HCl, 	ext{reflux}}$ is a Clemmensen reduction,producing butane $(C_4H_{10})$,an alkane.$4$. Electrolysis of sodium propionate $(CH_3CH_2COONa)$ via Kolbe's electrolysis produces butane $(C_4H_{10})$,an alkane.Since the question asks for a reaction that does not produce an alkene,and all options provided result in products other than alkenes,the question implies identifying the reaction that is chemically distinct or incorrectly framed. However,based on standard chemistry,none of these produce an alkene. Given the context of such multiple-choice questions,option $A$ is the most distinct as it involves oxidation,whereas others are reduction or coupling reactions.

Identify the reaction that does not produce an alkene.
