Derivatives of this molecule that contain oxygen include xanthophylls. For 10 points each:
[10h] Name this non-cyclic hydrocarbon with two double bonds used as the building block of terpenes. Dehydrogenating isopentane yields this molecule.
ANSWER: isoprene
[10e] This non-conductive material is the primary destination of isoprene mass-production. This flexible material used in car tires can be vulcanized to increase its strength.
ANSWER: rubber [accept latex]
[10m] Rubber friction on solid-state materials can induce this phenomenon where structural isomers rapidly interconvert. Other organic molecules can undergo the keto–enol form of this phenomenon.
