6. In methyl alcohol solution (CH3OH), bromine adds to ethylene to yield not only ethylene bromide but also Br CH2CH2 OCH3. How can you account for this? Write equations for all 7 Give the structure of the alkene that yields on ozonolysis: (a) CH3CH2CH2CHO and HCHO (b) CH3-CH(CH3)-CHO and CH3CHO (c) Only CHICO-CH (d) CH, CHO and HCHO and OHC CH-CHO (e) What would each of these alkenes yield upon cleavage by KMnO4 ? 8. Describe simple chemical tests that would distinguish between: (a) 2-chloropentane and n-heptane (b) 2-hexene and tert-butyl bromide (c) isobutane and isobutylene (d) allyl bromide and 1-hexene (e) sec-butyl alcohol and n-heptane (f) 1-octene and n-pentyl alcohol (g) tert-pentyl alcohol and 2,2-dimethylhexane (h) n-propyl alcohol and allyl alcohol (CH2=CHCHOH) Tell exactly what you would do and see. (Qualitative elemental analysis is a simple chemical test; degradation 9. A hydrocarbon, A, adds one mole of hydrogen in the presence of a platinum catalyst to form n-hexane. When A is oxidi/ed vigorously with KMnO4, e single carboxylic acid, containing three carbon atoms, is isolated. Give the structure and name of A. Show your reasoning, including equations for all reactions.
