Molecular Polarity

Q. Dinitrogen Diflouride, N2F2, is the only stable, simple inorganic molecule with an N=N bond. The Compound occurs in cls and transforms. (a) select which of the molecular shapes on N2F2 correspond to the cls and the trans form of N2F2 cls - dinotrogen flouride I II III trans—dinitrogen fluoride: I II III (b) Predict the polarity. if any. of each form. cis = polar: trans = polar cis = polar: trans = nonpolar cis = nonpolar: trans; = polar cis = nonpolar: trans = nonpolar

Molecular Polarity

Q. There are three different dichloroethylenses(molecular formula C2HCl2) which we can designate X, Y and Z. Compound S has no dipole moment, but compound Z does. Compounds X and Z each combine hydrogen to give the same product: C2H2Cl2(X or Z) + H2 --->ClCh2 ___CH2Cl What are the structures of X, Y and Z? Be sure to include Ione Pair Electrons. Would you expect compound Y to have a dipole moment? Yes No
