Brodbelt CH301 Homework 5 Due October 17, 2007 at 11:00 PM Please note that the terms electronic ar- rangement and electronic geometry mean the same thing. Also, the terms molecular shape and molecular geometry mean the same thing 001 (part 1 of 1) 10 points NF- 2 has (2, 3, 4) regions of high electron density and (2, 4, 6) bonded electrons. 1. 2; 6 2. 2; 2 3. 4; 6 4. 4; 4 5. 3; 4 6. 2; 4 7. 3; 2 8. 3; 6 9. 4; 2 002 (part 1 of 1) 10 points A molecule has one lone non-bonded pair of electrons on the central atom and three atoms bonded to the central atom. What is its electronic arrangement and its hybridization? 1. tetrahedral; sp 3 2. tetrahedral; sp 2 3. trigonal planar; sp 3 4. trigonal planar; sp 2 5. pyramidal; sp 2 6. pyramidal; sp 3 7. angular; sp 3 003 (part 1 of 1) 10 points The electronic arrangment is the same as the molecular shape when 1. the atoms are joined by sigma bonds. 2. there are more shared electrons than non- shared electrons. 3. the number of bonding orbitals equals the number of anti-bonding orbitals. 4. there are no lone pairs of electrons on the central atom....
