Acid base reactions – nucleophile (base) attacks electrophile (acid). … Nyob rau hauv luv luv, lub ntsiab lus ntawm feem ntau cov tshuaj tiv thaiv nyob rau hauv cov organic chemistry cuam tshuam cov ntws ntawm electrons los ntawm electron nplua nuj (nucleophilic) chaw mus rau electron pluag (electrophilic) qhov chaw.
Puas nucleophiles ib txwm tua Electrophiles?
Nucleophiles yog hom tshuaj uas pub ib khub ntawm electrons rau ib qho electrophile. … Ib qho kev tawm tsam nucleophilic feem ntau tshwm sim thaum ib hom tsiaj muaj hluav taws xob (cov nucleophile) "tawm tsam" hom tsis muaj hluav taws xob (cov electrophile, feem ntau yog carbocation), tsim ib daim ntawv cog lus tshiab ntawm nucleophile thiab carbocation.
Puas yog nucleophile lossis electrophile nres?
Hauv kev hloov pauv nucleophilic, ib qho hluav taws xob nplua nuj nucleophile daim ntawv cog lus nrog los yog tawm tsam ib qho hluav taws xob tsis zoo electrophile, ua rau muaj kev hloov pauv ntawm pawg lossis atom hu ua pawg tawm. Nucleophilic hloov pauv ntawm haloalkanes tuaj yeem piav qhia los ntawm ob qhov kev cuam tshuam.
Puas electrophile nres?
Ib qho tshuaj tiv thaiv electrophilic yog ib qho tshuaj tiv thaiv ntxiv uas tshwm sim vim qhov peb xav tias yog "tseem ceeb" molecule raug tawm tsamlos ntawm electrophile. Lub "tseem ceeb" molecule muaj thaj tsam ntawm cov hluav taws xob siab ceev uas raug tawm tsam los ntawm ib yam dab tsi nqa qee qhov txiaj ntsig zoo.
Puas yog nucleophile hnov mob nrog electrophile?
Anucleophile yog ib qho molecule uas tsim ib daim ntawv cog lus nrog nws cov tshuaj tiv thaiv tus khub (lub electrophile) los ntawm pub ob lub electrons rau daim ntawv cog lus. Nucleophiles yog Lewis hauv paus. Raws li koj tau pom, hydroxide yog ib qho piv txwv ntawm nucleophile uas ntxiv rau carbon dioxide. Hauv qab no yog qee qhov piv txwv ntawm nucleophiles.
