Be sure to answer all parts. dinitrogen difluoride, n2f2, is the only stable, simple inorganic molecule with an n=n bond. the compound occurs in cis and trans forms. (a) select which of the molecular shapes of n2f2 correspond to the cis and trans form of n2f2. i h5a ii h5b iii h5c cis-dinitrogen fluoride: 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

(a) The molecular shapes of cis and Trans forms of N2F2 are-

b) There is EN difference between N atom and F atom. Hence the molecule will have a bond dipole.

In Cis form two fluorine atoms are on the same side of N N bond. Hence, bond moment in N2F2 cis form) do not cancel each other. Thus the cis form is polar.

In the trans form two fluorine atoms are on the opposite side of N-N bond. Bond moment of NF cancels each other.

Thus: trans N2F2 is non polar molecule.

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
