Vedclass · Answer

(C) Acetylene $(HC \equiv CH)$ reacts with hypochlorous acid $(HOCl)$ in a two-step addition process.First,$HOCl$ adds across the triple bond to form an intermediate.With excess $HOCl$,the reaction proceeds as follows:$HC \equiv CH + 2 \, HOCl 	o [CHCl_2 - CH(OH)_2]$.This gem-diol intermediate is unstable and undergoes dehydration (loss of $H_2O$) to form $Cl_2CH - CHO$,which is Dichloroacetaldehyde.Therefore,the correct option is $C$.
