Wednesday 24th November Chemistry Class
Group Work:
At the start of class, Mr Carmichael put the class in separate groups of 3. Each group was given 2 sheets, one with many different molecules and another with classification groups.
We were asked to cut the molecules out and place them into the correct categories.
These categories were:
- The number of electron domains:
(1, 2, 3, 4, 5 or 6)
-The shape of the molecule :
(Linear, V-Shaped, Trigonal Planar, Pyramidal, Tetrahedral, Trigonal Bipyramidal, Octahedral)
-The strongest intermolecular force present:
(London Forces, Dipole-Dipole, Hydrogen Bonding)
The molecules to categorise were:
CO₂
NO₂
SeCl₂
H₂O
SO₂
F₂O
Cl₂
CO
NO
HF
ICl
CO₃²-
NH₃
PH₃
NH₄+
SiI₄
CBr₄
PBr₅
SCl6
Mind Map:
After matching each of the elements to the correct group in the 3 categories, we returned to our seats and were given the final assessment for the bonding unit : a concept map. For this, we were to arrange general to specific concepts on a map, with relationships between boxes related to each other. Mr Carmichael gave some ideas on the board that would need to be included. These were:
SL: HL:
-Metallic Bonding -5, 6 shapes
-Ionic Bonding -O₃
-Covalent Bonding -Hybridization
-Polarity -Formal Charge
-Electronegativity -Sigma & Pi Bonds
-Shape
-Electron domains
-Lewis Structures
-IMFs
-Physical Properties
-Carbon allotropes/giant covalent structures
-Lattice
-Length/strength
-Resonance
We were allowed to spend the end of class on the concept map, mostly brainstorming a list of concepts we were going to mention.
