WEEK 6 Inorganic compounds Flashcards
Compounds can be classified as:
Organic and inorganic
Inorganic compounds can be classified as:
-Covalent: (molecules)
-Ionic bonds (crystal structure)
Define inorganic compound
A compound that does not contain hydrocarbons, and is not typically found in living organisms
Name some simple compounds that contain carbon and are usually considered inorganic
Carbon monoxide and Carbon dioxide
Carbonates
Cyanide, cyanates and thiocyanates
carbides
Inorganic molecular(covalent) compounds are divided into:
-Anhydrides (acidic oxides)
-Peroxides
-acids (Hydracids & Oxoacids)
inorganic ionic compounds are divided into
-Ionic hydrides
-oxides (basic oxides)
-hydroxides
-salts (neutral salts, acidic salts)
Name these anhydrides using classical nomenclature
-N203
-N2O5
-SO2
-SO3
-nitrous anhydride
-nitric ||
-sulfurous ||
-phosphorous ||
-phosphoric ||
(-ous for low O content and -ic for high O content)
Name these anhydrides using classical nomenclature
Cl2O
Cl2O3
Cl2O5
Cl2O7
hypochlorous anhydride
chlorous anhydride
chloric anhydride
perchloric anhydride
Anhydride combine with water to form
Acidic oxides
example CO2 + H2O —> H2CO3 carbonic acid
Name the anhydrides using simple nomenclature
-N2O5
-Cl2O
-CO2
dinitrogen pentoxide
dichlorine monoxide
carbon dioxide
simple nomenclature cannot be used for ionic compounds. true or false?
true
Draw the lewis structure for the anhydrides:
carbon dioxide, sulfur dioxide, sulfur trioxide, dinitrogen trioxide, dinitrogen pentaoxide
confirm answer with lecture 4a inorganic
Draw the Lewis structure for:
nitrogen monoxide
nitrous oxide/dinitrogen monoxide
carbon monoxide
confirm answer with lecture 4a
What are peroxides?
binary compounds between oxygen and hydrogen, with a high proportion of oxygen
Name the peroxides
H2O2
Na2O2
Ba2O2
What are acids?
compounds containing one or more hydrogen atoms, which can be replaced by metal cations forming salts
What are the two types of acids?
Hydroacids
oxoacids
Write the systemic name and solution name of these hydracids
HF
HCl
H2S
What are hydracids?
Binary compounds formed between H &
a non-metal belonging to:
v group VIIA (halogens)
v group VIA (sulfur)
What are oxoacids?
Ternary compounds containing an H, O, and a non-metal
when H atoms are substituted by metal cations, oxoacids can form salts
H2CO3
HNO2
HNO3
H2SO3
H2SO4
name these oxoacids
carbonic
nitrous
nitric
sulfurous
sulfuric
Name these oxoacids
HClO
HClO2
HClO3
HClO4
H4SiO4
HClO hypochlorous acid
HClO2 chlorous acid
HClO3 chloric acid
HClO4 perchloric acid
H4SiO4 silicic acid
list the 5 acids of phosphorous, their formula and lewis structure
confirm with lecture 4a
