The other person who answered this question was wrong for coke and amorphous carbon, so if you go with their answer please switch the two. I just took a test with this question and got it partially wrong from folowing their answers.
Diamond - hard, three dimensional.
Coal - major source of today's medicine.
Combustion - major reaction type for alkanes.
Coke - from decomposition of coal.
Alkene - double bond.
Alkane - saturated hydrocarbon series.
Alkyne - triple bond.
Amorphous Carbon - soot, carbon black.
Graphite - soft, two-dimensional.
