Cyclopropene muaj 2 π electrons nyob rau hauv lub olefin. Li no cyclopropene yog electron meej thiab tsis aromatic . Ntawm qhov tod tes, rau cyclopropenyl cation , tus suav electron yog qhov tseeb rau ib qho aromatic qauv, thiab π electrons yuav raug delocalized nyob ib ncig ntawm lub nplhaib.
Xav txog qhov no, puas yog Cyclopropenyl cation aromatic?
Cyclopropenyl Cation Nws muaj ob pi electrons, li no tsuas yog ib daim ntawv cog lus ob. Nws yog ib qho kev zam rau txoj cai ntawm conjugation; nws yog aromatic . Cov cyclopropenyl cation muaj lub nplhaib tam sim no.
Ib tug kuj yuav nug, vim li cas Cycloheptatrienyl cation aromatic? electrons nyob rau hauv ib tug planar, cyclic pi system. Cov Cycloheptatrienyl anion muaj 8 electrons nyob rau hauv nws pi system. Qhov no ua rau nws antiaromatic thiab tsis ruaj khov heev. Cov Cycloheptatrienyl (tropylium) cation yog aromatic vim nws kuj muaj 6 electronics nyob rau hauv nws pi system.
Ib yam li ntawd, koj tuaj yeem nug, yog Cyclononatetraenyl cation aromatic?
Cyclononatetraenyl anion yog 10p aromatic qhov system. Ob tug isomers ntawm lub Cyclononatetraenyl hmoov anion paub: trans, cis, cis, cis isomer ("Pac-Man"-shaped) thiab tag nrho-cis isomer (ib qho convex enneagon).
Puas yog cyclopentadienyl radical aromatic?
Hauv chemistry, cyclopentadienyl tshuaj yog a radical nrog cov formula C5H5. Cov Cyclopentadienyl anion yog siv (formally related to the cyclopentadienyl radical los ntawm ib-electron oxidation) yog aromatic , thiab tsim cov ntsev thiab kev sib koom ua ke.
