solve Page: 6 20. In 1839 Charles Goodyear discovered a process by which both natural and synthetic rubbers are hardened. This process is called: a. diazotization b. vulcanization c. polymerization d. condensation 21. Electrophilic addition reaction of conjugated dienes that occur at high temperature and/or long reaction times (reversible conditions) are said to be under: a. 1,2- control b. kinetic control c. 1,4-control d. thermodynamic control 22. When an organic molecule is irradiated with ultraviolet radiation, the energy absorbed by the molecule corresponds to: a. the amount necessary to increase molecular motions b. the amount necessary to excite electrons from one c. the amount necessary to "flip" tho spin ot atomic in functional groups molecular orbital to another nuclei d. the amount necessary to strip a molecule of one electron to generate a radical cation consider the reaction below to answer the following questions. C O 23. The diene in the reaction isExplanation / Answer
20) The correct answer is Option b i.e. Vulcanization, which was discovered accidentally when he spilled the rubber on the floor
21) The correct answer is Option d i.e. Theromodynamic control
22) The correct answer is Option B i.e. the amount necessary to excite electrons from one molecular orbital to another
23) The diene in this reaction is A since it is having double bond in conjugation i.e. the compound
Cyclopenta-1,3-diene
