CH-= CH underset(NH_4Cl)overset(Cu_2 Cl_2)to A underset(Pd//BaSO_4)ove

1.	CH-= CH underset(NH_4Cl)overset(Cu_2 Cl_2)to A underset(Pd//BaSO_4)overset(H_2)to B ?What isB?
Answer» `C_2H_5Cl_2` `C_2H_4` `CH_2 = CH-CH = CH_2` `C_2H_6` SOLUTION :`2HC -= CH UNDERSET(NH_4Cl)OVERSET(CuCl_2)to underset("VINYL ACETYLENE")(HC-=C-CH = CH_2)underset(Pd//BaSO_4)overset(H_2)to CH_2 = CH - CH = CH_2`
