(2 points) Bond length (H-Br, H-F, H-I, H-Cl): ____HF, HCl, HBr, HI_____________ Polarity (H-Br, H-F, H-I, H-Cl): ____HI, HBr, HCl, HF_____________ 2. Fill in the chart. (7 points) VESPR formula Molecular geometry Molecular angle(s) AX 2 Linear 180 AX 4 Tetrahedral 109.5 AX 3 Trigonal Planar 120 What’s the VESPR formula of CH 3 Cl: AX 4 What’s the VESPR formula of CO 2 : AX 2 3. There are 3 Lewis structures for NCS-. Please complete these structures by drawing the correct number of electrons for each atom and the correct number of bonds between atoms, if necessary. (6 pts.) Which structure would be the most important and why? (2 pts)-Minimize formal charge on each atom. (3 rd is eliminated)-Negative formal charge prefers the atom with the highest ionization energy (N) PERIODIC TABLE OF THE ELEMENTS...
