|
Considering reaction of Nitration and Sulfation, does nitric acid or sulfuric acid act as base? Why?
|
Nitric Acid does, because sulfuric is stronger.
|
|
|
What does Frieedl-Crafts Alkylation make? What is the electrophile?
|
makes alkyl benzenes, the electrophile is the R group
|
|
|
General Friedl-Crafts reaction
|
Benzene + 1_RCL 2_AlCl3--->benzene with r + HCl
|
|
|
what is the interaction of aluminum and chlorine in F-C Alkynation`
|
chlorine donates electron pair to empty p orbital on aluminum
|
|
|
which cyclalkanes give entire carbocations in Friedel-Crafts alkylation/acytation?
|
2 and three degrees
|
|
|
What works for F-L alkylation? What doesn't?
|
Ch3Cl, 1 degree, 2 degree, 3 degree all work, aryl halides and vinyl halides do not because they leave aryl carbocations and vinyl carbocations, the worst kinds.
|
|
|
Two formerly known ways of making carbocations and their exact product
|
alkene+H2S04=2 degree cyclic carbocation
alcohol + H2SO= 3 degree carbocation |
|
|
in Friedel-Crofts alkylation, what do you do with the electrophiles once you get them?
|
add them to Benzene to get benzene and R
|
|
|
Friedl-Crofts Acylation=general
|
benzene + 1.ROCL (acid chloride) 2.AlCl3 to get acyle benzene (COR on a benzene)
