•Is this molecule polar or non-polar (give a reason)?
F and Cl are both more electronegative than C, but the bond
polarities do not cancel and the molecule is polar. e. (6 pts) A Lewis dot representation of N2 O is shown below. Is this the best possible
representation? If not, draw an alternative and give a reason why yours is better. Formal charges are -2, +1, +1. Better representations are -1 +1 0 or
0 +1 -1 page 3 Name: ___________________________
