Question
Chapter 4, Problem 7CTQ
Interpretation Introduction
Interpretation:Overall nonpolar molecule in figure 4.5 should be encircled.
Concept introduction:Dipole moment is measure of bond polarity in molecule. It is defined as product of charge and distance of separation between opposite charges. Polar molecules consist of dipole moments due to presence of charges in them whereas non-polar molecules do not have dipole moments.

Re-sketch the diazene molecule and label all bond dipoles (with the arrow pointing from the most electronegative atom to the least electronegative atom).
Show using vector sums that this geometric isomer of diazene is non-polar.
A. Classify the following molecules as polar or non-polar (write below the chemical
formula in the first column. Explain your answer in terms of the (a) Lewis
structure (b) molecular geometry and (c) bond polarity. (You can add rows if
you need more spaces for your explanation.)
Hint: Although I am not asking you to give the no. of bonding and non-bonding
pairs, you have to do it to be able to identify the electron pair geometry and
molecular geometry.
Note: Items #1 to #4 are hypothetical molecules. The number of valence
electron/s of the hypothetical atoms are given in parenthesis.) There is no need
to give actual molecules to represent them.
