Vedclass · Answer

(C) Let us analyze each reaction:$(A)$ Dehydrohalogenation of vicinal dihalides with $Alc. KOH$ followed by $NaNH_2$ gives an alkyne.$(B)$ Reaction of $CH_3-CCl_3$ with $Ag$ powder is not a standard method to produce $CH_3-C \equiv C-CH_3$. The reaction of $CH_3-CCl_3$ with $Ag$ typically leads to coupling products or other derivatives,not an alkyne.$(C)$ Dehalogenation of vicinal dihalides with $Zn$ dust in alcohol gives an alkene $(CH_3-CH_2-CH=CH_2)$,not an alkyne.$(D)$ Kolbe's electrolysis of sodium maleate or fumarate gives ethyne $(HC \equiv CH)$.Note: Both $(B)$ and $(C)$ do not produce an alkyne. However,in the context of standard textbook problems,$(C)$ is the most direct example of a reaction producing an alkene instead of an alkyne from a vicinal dihalide.

Which of the following reactions does not give an alkyne?
