Chapter 6: Reactions of Alkenes : Addition Reactions |
| Qu 1: | Show the major products, with stereochemistry where applicable, for the reactions of : | ||
(a) propene and (b)
1-methylcyclohexene with each of the following :
|
|||
| Qu 2: | Using diagrams, mechanisms with curved arrows, and / or short paragraphs, explain the following observation: | ||
|
|||
| Qu 3: | The following paragaraph describes a series of reactions on a series of unknown but related compounds: | ||
| An hydrocarbon A was analyzed by combustion analysis. 0.01g of A gave 0.03217g of CO2 and 0.011g H2O. | |||
| A was added
to conc. H2SO4 and the non-polymeric portion of the
organic extract was found to contain small amounts of the starting material
A and three other isomeric hydrocarbons, B, C and D.
All four compounds were further investigated chemically by their reactions
with H2 / Pt and with HBr (dark). Reaction of either A or D with H2 / Pt gave ethylcyclobutane. Reaction of A with HBr (dark) gave E, a secondary bromide whereas reaction of D with HBr (dark) gave F, a tertiary isomer of E. Reaction of either B or C with H2 / Pt gave methylcyclopentane. Reaction of B or C with HBr (dark) gave G. What are A
- G ? |
