Explain which of these reactions would provided a better synthesis of 3-hexanone. CH_2CH_2C=CCH_2CH_3 CH_2C = CCH_2CH_2CH_3
The Wittig synthesis of the following alkene would ideally
employ which carbonyl compound?
The Wittig synthesis of the following alkene would ideally employ which carbonyl compound? a) propanol b) acetone c) 2,4-dimethyl-3-pentanone d) 2-methyl-3-hexanone
In order to synthesize 5-methyl-2-hexanone via acetoacetic ester synthesis, which of the following compounds should be reacted with the enolate ion generated by the reaction of ethylacetoacetate with sodium ethoxide? A) 2-methylpropanal B) isobutyl bromide C) 1-bromo-3-methylbutane D) 2-methyl-1-propanol E) none of the above Correct answer is B. Please explain why
Please describe the tests you would use to distinguish between aceton, 2-hexanone and 3-hexanone.
Which of the following reactions would constitute a reasonable
synthesis of propyl acetate?
In each reaction box, place the best reagent and conditions from the list below. 3-Hexanone should be the exclusive final product. (A reagent may be used more than once.) Incorrect. These reactions will produce 2-hexyne which, when hydrated, will produce a mixture of 2-hexanone and 3-hexanone. You were asked to find a reaction sequence producing exclusively 3-hexanone.
why would it be impossible for a ketone to have a name like 3 - methyl - 1 - hexanone
2. Which would you expect to be a better Lewis acid, Explain. BCl3 or B(CH3)3? BeCl2 or BCl3? B(nBu)3 or B(tBu)3 BF3 or BCl3 or BBr3
2. Which solvent would be better used to carry out the reactions shown below? Circle one. HSSH Methanol or DMF
