The structure below is the cyclic ether (epoxide), butene oxide:
(1)
CH3CH₂
-CH₂
butene oxide
How could this compound be prepared from but-1-ene?
Explain why butene oxide is much more reactive than its isomer,
tetrahydrofuran, which is also a cyclic ether:
H₂C-CH₂
H₂C
CH₂
tetrahydrofuran
Illustrate how butene oxide reacts with ammonia, showing details of
the mechanism leading to the final product, C4H11 NO.
2,4-D is a synthetic auxin (a plant hormone) used in the control of broadleaf weeds, and one of the most widely used herbicides in the world. It is produced commercially by the following reaction:
chloroacetic acid + dichlorophenol → hydrochloric acid + 2,4-D
C2H3ClO2 + C6H4Cl2O → HCl + C8H6Cl2O3
How much chloroacetic acid does it take to manufacture 5.18 grams of 2,4-D?
