1. H2 is a non-polar, due to same atoms are bonded by sharing of 1 electron each.
2. Br2 also non-polar, Br has 7 valence electrons, by sharing of one valence electrons each of Br, get completed octet and having 3 non-bonding pairs of electrons on each Br.
3. BrCl is Polar, Both has 7 valence electrons, by sharing of one valence electrons each of Br and Cl, get completed octet and having 3 non-bonding pairs of electrons on each Br. Due to more electronegative of Cl than Br electron density of B.P. electron is shifted towards Cl, and Cl get slightly negative and Br slightly positive.
4. C has 4 and O has 6 valence electrons, from 2 electron of C and 4 from O, are shared and get triple bond and 1 non bonding electron pairs resided on each, polar due to difference in electronegativity.
5. HCl, is a polar.
6. CO2 is linear and centrosymmetric therefore dipole moment will be zero and it is non-polar.

Use Lewis dot structure and VSPER model to determine whether the following molecules is polar of nonpolar (does the molecule has an overall molecular dipole) araw the Lewis dot structure first, determine the electron pair geometry, then determine the molecular geometry. Use the flow chart we completed in class. a. CHCI b. PCIE C. CO d. SF e. IFS f. CHOCH 8. CCI,H h. H,сон
5.) Draw Lewis dot structures for the following molecules below. Next, draw the three dimensional structure for each molecule using lines, dashes and wedges. Write what the bond angles are in each case. Calculate the difference in electronegativity (AEN) between each pair of bonding atoms. Draw dipoles for each bond in the molecule and draw a net dipole if one exists. In there is no net dipole, write "NO NET DIPOLE". Use this information to determine if the molecule is...
Procedure: For Part 1, write the Lewis Dot (or Electron Dot) structure for each atom, followed by the ions that each element would form, the compound that would be formed from the combination of the two elements and finally the Lewis Dot structure for the compound. For Part 2, show the Lewis Dot structure for each molecules, its AXE designation and finally its Electron Pair/ Geometric Shape geometries. Also indicate any partial charges that may exist on that molecule. PART...

Worksheet 8.1“Lewis Dot Structures and Formal Charge Calculations” 1. Goal: Draw Lewis Dot Diagrams and determine either formal charge or bond polarity. 2. Why: to understand chemical bonding, you must be able draw three dimensional representations to show bond angles and strength of chemical bonds. Students also need to be able to use Calorimetry equations to calculate enthalpy of reactions. Atomic number (2) Chemical symbol Be1 9.01 - Atomic mass 3A 4A 5A 6A beryllium (defined in section 4.9) 13...
