Benzene tuaj yeem nkag mus hloov. Piv txwv li: Nitration thiab Suphonation ntawm Benzene . Yog li ntawd ua tsis yog raug tshem tawm cov tshuaj tiv thaiv . Benzene ua tsis tau raug tshem tawm cov tshuaj tiv thaiv.
Hauv qhov no, cov tshuaj benzene tau txais dab tsi?
Benzene ruaj khov ntau dua li qhov xav tau. Qhov kev ruaj ntseg ntxiv txhais tau tias benzene yuav tsis yooj yim nkag mus ntxiv cov tshuaj tiv thaiv . Qhov ntau loosely tuav electrons yog qhib rau tua los ntawm electrophiles. Yog li ntawd, tus yam ntxwv cov tshuaj tiv thaiv ntawm benzene yog electrophilic hloov.
Ib tug kuj yuav nug, puas yog benzene tau txais kev hloov pauv nucleophilic? Vim lub xub ntiag ntawm electron huab ntawm delocalised electron rau tshuaj benzene nplhaib nucleophilic kev tawm tsam yog qhov nyuaj thiab yog li ib txwm ua tsis yog tau txais cov tshuaj tiv thaiv nucleophilic hloov pauv . Yog li nyiam electrophilic hloov tshwm sim.
Xav txog qhov no, puas yog benzene tau txais cov tshuaj tiv thaiv ntxiv?
Benzene tsis yog raug cov tshuaj tiv thaiv ntxiv , vim nws aromaticity uas muab cov tshuaj benzene nplhaib txaus stability. yog ntxiv cov tshuaj tiv thaiv yuav siv qhov chaw rau tshuaj benzene nplhaib nws poob nws aromaticity. Vim tshuaj benzene yog ruaj khov nyob rau hauv nws tus kheej thiab tsis tuaj yeem xoob hydrogen.
Vim li cas benzene txaus siab rau kev hloov pauv hloov?
Benzene muaj delocalized electrons. Yog li ntawd, nws yog electron nplua nuj. Yog li ntawd nws yog qhov txaus nyiam heev rau electrophiles.

Puas yog lub zog tso tawm lossis absorbed hauv cov tshuaj tiv thaiv exothermic?
Ib qho tshuaj tiv thaiv uas lub zog tawm mus rau ib puag ncig yog hu ua cov tshuaj tiv thaiv exothermic. Nyob rau hauv hom tshuaj tiv thaiv no lub enthalpy, los yog khaws cia chemical zog, yog qis dua rau cov khoom tshaj cov reactants. Thaum ammonium nitrate yaj nyob rau hauv dej, lub zog yog absorbed thiab dej txias
Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Puas yog cov tshuaj pleev xim sib xyaw cov tshuaj tiv thaiv?
Tsis yog txhua qhov kev hloov xim qhia tias muaj tshuaj lom neeg. Kev sib xyaw xim tsuas yog hloov lub cev. Tsis muaj cov khoom tshiab tsim. Vim hais tias lub cev thiab tshuaj pleev xim ntawm cov xim siv los ua xim sib txawv, tus nqi thiab qhov deb ntawm lawv mus raws li daim ntawv so ntswg sib txawv, ua rau cov xim sib txawv
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
