U3 Lesson 3 Check for Understanding VSEPR:
Directions:
Using the drawings from CFU 3, Identify how many bonding domains(bonds) and nonbonding domains(lone pairs). Then name the Shapes of each drawing
**Remember a double or triple bond counts as only 1 bonding domain
| F2 bonding domains: 0 nonbonding domains:0 Shape: linear | H2 bonding domains:0 nonbonding domains:0 Shape: linear | HF bonding domains:0 nonbonding domains:0 Shape: linear | NH3 bonding domains: 3 nonbonding domains: 1 Shape: trigonal pyramidal |
|---|---|---|---|
| NF3 bonding domains: 3 nonbonding domains: 1 Shape: trigonal pyramidal | SiF4 bonding domains: 4 nonbonding domains: 0 Shape: tetrahedral | CCl4 bonding domains: 4 nonbonding domains: 0 Shape: tetrahedral | H2O bonding domains: 2 nonbonding domains: 2 Shape: tetrahedral |
| CO bonding domains: 0 nonbonding domains: 0 Shape: linear | N2 bonding domains:0 nonbonding domains: 0 Shape: linear | O2 bonding domains:0 nonbonding domains:0 Shape: linear | we do not have to do this one |
| BeCl2 bonding domains: 2 nonbonding domains: 6 Shape: linear | no do | BF3 bonding domains: nonbonding domains: 0 Shape:trigonal planar | dont have to do |
| PO43− bonding domains: 4 nonbonding domains: 0 Shape: tetrahedral | SO42− bonding domains: 4 nonbonding domains: 0 Shape: tetrahedral | CN− bonding domains: 0 nonbonding domains: 0 Shape: linear | ClO3− bonding domains: 3 nonbonding domains: 1 Shape: trigonal pyramidal |
Which of the above shapes are symmetrical (have no lone pair on the central atom)?
Which of the above shapes are asymmetrical (have lone pair on the central atom) ?
Do lone pair electrons take up more space than a bonding pair of electrons? yes no
