purification, extraction and manufature
Alumina from bauxite
bauxite is the primary ore of alumina, which is used to make aluminium
-
-
Titanium from its ore
rutile is the primary ore of titanium, which is used to make titanium
uses: important pigment, whiting, and polishing abrasive.
Hall–Héroult
-
-
-
Cryolite lowers the melting point of the ore and make it more conductive in nature so as to carry out electrolysis of the ore in Hall- Heroult process
-
-
membrane cell
makes use of brine and a membrane cell with positive and negatively charged electrodes. The anode (negative charge) oxidizes the chloride ion, which loses an electron to become free chlorine gas
Straight-chain, branched and cyclic alkanes and alkenes
the difference between straight and branched chain alkanes is that in straight-chain alkanes, all the carbon atoms bond with each other forming a continuous chain whereas branched-chain alkanes have side chains attached to a continuous carbon chain

-
-
sigma & pi bonds
Alkenes contain a double bond that is composed of one sigma and one pi bond between two carbon atoms.
-
alkane/ene
-
alkane: An unsaturated hydrocarbon containing at least one carbon—carbon triple bond between two carbon atoms.
