Chemical formulation!Metallic hydrides:
Formula “Stock” name “Systematic” name
Lithium hydride
Iron dihydride
FeH3
MgH2
Extension task: add these to the table:• Sodium hydride• RbH• Copper(II) hydride
Why does ´lithium hydride´ have the same name in both columns?
Formula Name of acid Name of gas
H2S
Hydroselenic acid
Hydrogen fluoride
HCl
Hydrobromic acid
Hydrogen iodide
Non-metallic hydrides:
Formula Name of hydride
BH3
Diborane
Methane
Ammonia
Extension task: Add these to the correct table:• HAt• H2P
Which other names could we give to water?
Formula “Stock” name “Systematic” name
FeO
Diiron trioxide
Copper(I) oxide
Copper oxide
Aluminium oxide
Metallic oxides:
Extension task: Why does the stock name for ´aluminium´ oxide not show its valency? Which valencies can ´chlorine´ have?
Formula “Stock” name “Systematic” name
Dichlorine monoxide
Cl2O3
Chlorine(V) oxide
Chlorine(VII) oxide
SO2
Sulphur trioxide
Non-metallic oxides:
Binary salts (one cation and one anion):
Formula “Stock” name “Systematic” name
NaCl
Magnesium chloride
Iron sulphide
Nickel(III) nitride
Formula “Stock” name “Systematic” name
Sodium hydroxide
Sn(OH)2
Manganese(III) hydroxide
Gold trihydroxide
Hydroxides (the [OH] anion has an ox. State of -1):
Extension task: Explain what is wrong with ´BaOH´?
Oxyacids:Contains ´hydrogen…non-metal…oxygen´
Valency Anion Oxyacid
Lowest Hypo………ite Hypo………ous acid
…ite …ous acid
…ate …ic acid
Highest Per………ate Per………ic acid
Formula Traditional name
HClO
HClO2
HClO3
HClO4
Formula Traditional name
Hypobromous acid
Bromous acid
Bromic acid
Perbromic acid
Ext: Show the valency of chlorine and bromine in each oxyacid.
