What halides would undergo E2 dehydrohalogenation to give the following pure alkenes? a. hex-2-ene
4. Which of the alkyl chlorides listed below undergoes dehydrohalogenation in the presence of a strong base to give pent-2-ene as the only alkene product? A) 1-chloropentane B) 2-chloropentane C) 3-chloropentane D) 1-chloro-2-methylbutane E) 1-chloro-3-methylbutane
For the following dehydrohalogenation (E2) reaction, draw the major organic product(s), including stereochemistry.What product(s) are expected in the ethoxide-promoted B-elimination reaction of 1-chloro-1-methylcyclohexane? Omit ions, salts, and ethanol from your response.
For the following dehydrohalogenation (E2) reaction, draw the
Zaitsev product(s), showing the stereochemistry clearly. If there
is more than one organic product, both products can be drawn in the
same box.the hint:Consider that the reaction is an elimination in the presence of
a relatively small base to give the Zaitsev product, which is the
most stable. Also consider the stereochemistry of the reactant and
that the elimination must be anti-periplanar.
7, (10) Give the alkyl halide which would give only the alkene shown by way of an E2 elimination (one alkyl halide for each alkene):
answer 1. A hydrocarbon is an organic compound consisting entirely of carbon and hydrogen atoms. Pentane and pent-1-ene are two examples. a) Describe a test which would distinguish between pentane and pent-1-ene. Include in your ans the reagent, and the observations for the reaction. (3 marks) b) Pent-2-ene is an isomer of pent-1-ene. Draw the two stereoisomers of pent-2-ene and name them. (4 marks) c) Explain why pent-2-ene exhibits stereoisomerism whereas pent-1-ene does not. (4 marks)
Question 24 Which alkene(s) can undergo acid-catalyzed hydration to give the following product? OH only only
6. Which experimental evidence would not support the Sn2 mechanism for the reaction between (S)-2-bromooctane and sodium acetylide (aka ethynylsodium)? (A) Only (S)-3-methyl-1-nonyne is observed as a product. (B) The reaction rate decreases tenfold when the concentration of bromooctane is reduced from 1.0 M to 0.1 M (C) The reaction rate doubles when the concentration of sodum acetylide is doubled. (D) The rate of reaction is increased by switching from sodium to potassium acetylide. 7. Which alcohol must undergo a...
