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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
