Chemical Reactions and Chemical Bonds Flashcards
Inside the molecule
Intra
Between 2 molecules
Inter
Stronger bond force
Intra
Weaker non-bonding force
Inter
Holds the atom together within a molecule.
Intra
Intramolecular Forces (2 types)
Ionic and Covalent
Transfer of electrons between a cation and anion
Ionic bond
Sharing of electrons
Covalent bond:
Unequal sharing of e-
Polar
Equal sharing of electrons
Non-polar
What are the 2 types of intermolecular forces?
Hydrogen and Van der Waals
The attractive force between a hydrogen atom covalently bonded to a very electronegative atom
Hydrogen Bonding
Attraction between a partial positive and a partial negative charge
Hydrogen Bonding
Weak attractive force between atoms or non-polar molecules
Van der Waals Bonding
Strongest to Weakest
COVALENT BONDING
IONIC BONDING
HYDROGEN BONDING
VAN DER WAALS
What are the types of chemical reactions?
Synthesis
Decomposition
Single Displacement
Double displacement
Combustion
A + B →AB
Direct Union /Synthesis
AB →A + B
Decomposition
Double Replacement
AB + CD →AC + BD
A + BC →AC + B
Single Replacement
NaCl + AgNO3 →NaNO3 + AgCl(s)
Double Replacement
H2O2 →H2O + O2
Decomposition
2 KI + Cl2 →2 KCl + I2
Single Replacement
2H2 + O2 →2 H2O
Direct Union /Synthesis
A combination of two or more simple reactants and result in a single, more complex product
Synthesis
Breaks down a compound into two or more simpler substances
Decomposition
Element is substituted for another
element in a compound, generating a new element and a new compound as products.
Single Replacement
Reaction begins with two compounds as a reactant. Metals, usually aqueous ions, exchange resulting in two or new products
Double Replacement
A reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.
Combustion
Combustion reactions must involve _____.
Oxygen/ O2
Reduction
GEROA
Gain of electrons – Reduction – Oxidizing Agent
Oxidation
LEORA
Loss of Electrons– Oxidation – Reducing Agent
A + e- → A-
Reduction
A-→A + e-
Oxidation
Reaction between strong acid and strong base that forms a salt and water
Neutralization
