Bonding Basics
This type of bond forms when electrons are shared equally between two atoms.
A) Ionic bond
B) Polar covalent bond
C) Metallic bond
D) Nonpolar covalent bond
What is a (D) nonpolar covalent bond?
The weakest intermolecular force, caused by temporary electron fluctuations.
What are London dispersion forces?
The shape of a molecule with 2 bonding pairs and no lone pairs (e.g., CO₂).
What is linear?
A molecule with polar bonds but no overall dipole (e.g., CO₂).
A) The bonds are nonpolar and cancel out
B) The molecule is linear, and the bond dipoles cancel each other
C) It contains only ionic bonds
D) The atoms have the same electronegativity
What is B) The molecule is linear, and the bond dipoles cancel each other?
This acid has the formula HClO₂.
What is chlorous acid?
The bond in NaCl involves the complete transfer of electrons, making it this type.
What is an ionic bond?
Water's high boiling point is due to these strong attractions between molecules.
What is hydrogen bonding?
The bond angle in a trigonal planar molecule (e.g., BF₃).
What is 120°?
A trigonal pyramidal molecule that is nonpolar.
What is PH3?
The name for the acid H₃PO₄.
What is phosphoric acid?
Nitrogen gas (N₂) is so stable because it contains this strong type of bond.
What is a triple bond?
What is the difference between intermolecular and intramolecular forces?
What are attractions between different molecules, while intramolecular forces are the bonds within a single molecule that hold atoms together.
Build CO2 (Carbon dioxide) using the building blocks
Check with Maria, Rana, or Gabriel
The reason O₂ is nonpolar despite being diatomic.
What is "equal electronegativity → equal electron sharing"?
This base with the formula Fe(OH)₃ is named using the stock system.
What is iron(III) hydroxide?
The bond angle in a tetrahedral molecule (e.g., CH₄).
What is 109.5°?
Oil and water don't mix because oil lacks polarity to interact with water's hydrogen bonds.
TRUE or FALSE?
What is true?
Why H₂O is bent (not linear) despite having only 2 bonds.
What is "lone pairs repel more than bonding pairs"?
Most reactive element
What is fluorine?
The most toxic acid in the world.
What is hydrofluoric acid?
This property determines whether a covalent bond is polar or nonpolar.
What is electronegativity difference?
The order of strength for intermolecular forces (strongest to weakest).
What is hydrogen bonding > dipole-dipole > London dispersion?
Build all 5 VESPR structures and name a molecule associated with it
What is H2O (Bent), NH3 (Trigonal pyramidal), CH4 (Tetrahedral), BF3 (Trigonal Planar), CO2 (Linear)?
What is the name of group 17 on the periodic table and what makes it unique from the rest?
What is halogens, and they are unique because they are highly reactive nonmetals with 7 valence electrons, needing only one more to complete their outer shell?
The correct IUPAC name for the compound called “H2S”.
What is hydrogen sulfide.
