Peb paub tias benzene muaj cov qauv hexagonal nyob rau hauv uas tag nrho cov pa roj carbon atoms yog sp 2 hybridized, thiab tag nrho cov carbon- carbon bonds yog sib npaug ntawm qhov ntev. Raws li qhia hauv qab no, cov seem cyclic array ntawm rau p-orbitals (ib qho ntawm txhua cov pa roj carbon) sib tshooj kom tsim tau rau 6 molecular orbitals, peb daim ntawv cog lus thiab peb cov tshuaj tiv thaiv.
Dab tsi yog cov pa roj carbon hauv benzene?
Cov benzene molecule yog tsim los ntawm rau cov pa roj carbon atomskoom nrog hauv lub nplhaib planar nrog ib lub atom hydrogen txuas rau txhua tus. Vim tias nws tsuas muaj cov pa roj carbon thiab hydrogen atoms, benzene yog cais raws li hydrocarbon.
Muaj pes tsawg hom carbon nyob hauv benzene?
Benzene, C6H6, feem ntau yog kos li lub nplhaib ntawm six carbon atoms, nrog alternating ob daim ntawv cog lus thiab ib daim ntawv cog lus: Daim duab yooj yim no muaj qee qhov teeb meem, txawm li cas los xij.
benzene ua los ntawm dab tsi?
Benzene yog ib qho tseem ceeb organic chemical compound nrog cov tshuaj formula C6H6 thiab nws cov molecule yog tsim los ntawm 6 carbon atoms koom rau hauv ib lub nplhaib nrog 1 hydrogen atom txuas rau txhua carbon atom.
YPuas yog benzene ib qho saturated carbon?
Aromatic hydrocarbons yog ib chav tshwj xeeb ntawm unsaturated hydrocarbon raws li rau lub nplhaib moiety hu ua benzene. Lub saturated hydrocarbon cyclohexane tau hloov mus rau hauv cov tshuaj tsw qab hydrocarbon benzene los ntawm kev ntxiv peb alternating carbon-carbon ob daim ntawv cog lus, raws li qhia hauv daim duab 1.11.

Nyob rau hauv cov sulfonation ntawm benzene cov active hom kev koom tes yog?
Sulphonation ntawm benzene yog ua los ntawm SO3 (electrophile). Yuav ua li cas yog hom kab mob hauv Sulphonation ntawm benzene? Yog li, lub zog electrophile hauv sulfonation ntawm benzene yog sulphur trioxide. Sulphonation ntawm benzene yog dab tsi?
Puas yog tag nrho cov kab mob nyob rau hauv?
Tsis yog txhua tus kab mob muaj lub hnab ntawv. Cov hnab ntawv feem ntau yog muab los ntawm ib feem ntawm cov cell membranes (phospholipids thiab proteins), tab sis suav nrog qee cov kab mob glycoproteins. Lawv tuaj yeem pab cov kab mob kom tsis txhob muaj lub cev tiv thaiv kab mob.
Nyob rau hauv uas carbon allotrope yog tag nrho cov electrons localised?
In pob zeb diamond, tag nrho plaub sab electrons ntawm txhua carbon atom yog 'localized' ntawm cov atoms hauv covalent bonding. Kev txav ntawm electrons raug txwv thiab pob zeb diamond tsis ua hluav taws xob tam sim no. 4 allotropes ntawm carbon yog dab tsi?
Leej twg detering nyob rau hauv tag nrho cov nyob ntsiag to nyob rau sab hnub poob pem hauv ntej?
Detering yog tus neeg ua liaj ua teb los ntawm Txhua Tus Neeg Tsis Txaus Siabntawm Sab Hnub Poob los ntawm Erich Maria Remarque. Nws muaj siab mos siab muag, tshwj xeeb tshaj yog thaum nws los txog rau nees. Nws muaj kev kub ntxhov loj heev thaum nws hnov cov nees quaj thiab txawm sim tua lawv kom kawg lawv txoj kev txom nyem.
Puas yog tag nrho cov neeg zoo tag nrho narcissists?
Narcissist yeej muaj peev xwm nqa tau cov yam ntxwv ntawm kev ua tau zoo heev, xav tswj txhua yam, xav kom lawv lub ntiaj teb nyob rau hauv kev txiav txim zoo, tab sis tsis yog txhua tus narcissist, qee qhov kev tsis sib haum xeeb tib yam uas ib tug neeg tuaj yeem ua tau zoo heev thiab txawm tias tej zaum ntau dhau lawm, xav tau yam nyob hauv … Puas yog perfectionism ib daim ntawv ntawm narcissism?
