isoprene - Great Lakes - Buzzpoints App

Question

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.

ANSWER: tautomerization [or word forms like tautomers]
