Explanation:
1. from decomposition of coal → Coke
Coke is obtained by burning of coal at high temperature.
2. triple bond →Alkynes
Alkynes are hydrocarbons with triple covalent bond between the carbon atoms.
3.hard, three dimensional → diamond
Diamond is an alotropic form of carbon which have 3-D structure which accounts for its hardness.
4.major source of today's medicine → coal
Many medicine or chemicals used in medicinal industries are obtained by distillation of coal such as : salicyclic acid derived tar, phenols etc.
5.double bond → alkene
Alkenes are hydrocarbons with double covalent bond between the carbon atoms.
6.soft, two dimensional → graphite
Graphite is an alotropic form of carbon which have 2-D or layered structure which accounts for its softness.
7.saturated hydrocarbon series → alkanes
Hydrocarbons with single bond and no double or triple bond is present in between carbon atoms.
8.major reaction type for alkanes → combustion
When alkanes react with oxygen or burn in the atmosphere of oxygen they give water and carbon-dioxide
9.soot, carbon black → amorphous carbon
Amorphous carbon is an form of carbon without any structure or shape
