1) How are the properties of molecules related to the 3D distribution of electrons and Coulomb’s law?

2) Match these six compounds to the description of electron distribution between the atoms. Choose either a) transferred electrons b) unequal distribution of electrons c) electrons equally distributed. Compounds to be matched are listed below.
-Cl2   -AgCl - AgNO3   -PCl3 -C2H6O - CH4

3) Which bond is the most polar? H-N, H-F, H-O, H-C

4) Fill in the blanks for each statement, choosing either polar covalent or nonpolar covalent for the first blank and polar or nonpolar for the second blank for each sentence.

Sentence 1- The bonds in BeCl2 are __________. The overall molecule is _____________.

Sentence 2- The bonds in H2O are ___________. The overall moelcule is ____________.

Sentence 3- The bonds in O2 are ____________. The overall molecule is ____________.

5) Which of these molecules is polar? (Select all that apply.) ----> PCl3, SO2, CO2, CH2Cl2

6) Which of these substances has a smell? (Select all the apply) -------> PbCl2, HOCl, Pb, Si

7) Which of these atoms has the strongest attraction for valence electrons? Choose one. Lithium, Flourine, or Chlorine?

8) Make two drawings to illustrate of CH3OH and C2H4 do or do not have a smell. Be sure that your drawings clearly illustrate the polarity of the bonds and the overall molecule.

Homework Answers

Answer #1

Ans.1. Columb's law tells about the force of attraction or force of repulsion between two opposite charge.

Ans 2. Cl2 = equally distributed, AgCl = transferred electron

AgNO3 = transferred electron PCl3 = unequal distribution of electron

C2H6O = unequal distribution of electron CH4 = unequal distribution of electron

Ans 3. HF bond is more polar because flurorine is most electronegative.

Ans 4. Bond in BeCl2 is non polar covalent, and overall molecule is non polar

Bond in H2O is polar and overall molecule is polar

Bond in O2 is non polar covalent and overall molecule is non polar
