Answer

and AsCl3\mathrm { AsCl } _ { 3 }

Explanation

Solution

HC≡CH+AsCl3⟶ClHC 2-chlorovinyl dichloroarsine  (Lewsite) =CHAsCl2\mathrm { HC } \equiv \mathrm { CH } + \mathrm { AsCl } _ { 3 } \longrightarrow \underset { \substack { \text { 2-chlorovinyl dichloroarsine } \\ \text { (Lewsite) } } } { \mathrm { ClHC } } = \mathrm { CHAsCl } _ { 2 }
