There are three different dichloroethylenes (molecular for- mula C,H,Cl,), which we can designate X, Y, and Z. Compound X has no dipole moment, but compound Z does. Compounds X and Z each combine with hydrogen to give the same product: C,H,Cl, (X or Z) + H, → CICH,-CH,CI What are the structures of X, Y, and Z? Would you expect com- pound Y to have a dipole moment?

In contrast to the cyanate ion (NCO-), which is stable and found in many compounds, the fulminate ion (CNO-), with its different atom sequence, is unstable and forms compounds with heavy metal ions, such as Ag+ and Hg2+, that are explosive.
