Yes, dej yog nucleophile. Dej yog ib qho nucleophile thiab electrophile.

Vim li cas dej thiaj yog nucleophile zoo?

Nucleophiles yog tag nrho cov ions tsis zoo, lossis lwm yam muaj zog - them rau qhov chaw ntawm lub molecule. Dej pom tseeb tsis muaj tus nqi tsis zooTxawm li cas los xij, cov pa oxygen ntau dua electronegative dua hydrogen, thiab yog li cov pa atom muaj qhov loj heev - them rov qab nws ob leeg ib leeg.

YIs H2O nucleophile?

Dej (H2O H 2 O) tuaj yeem ua lub nucleophile thiab electrophile. Muaj ib khub ntawm electrons ntawm cov pa atom uas tso cai rau nws pub dawb electrons los ua daim ntawv cog lus uas feem ntau nws tuaj yeem ua raws li nucleophile.

Puas yog dej yog nucleophile zoo tshaj plaws?

Cov molecule ntawm dej tsuas muaj ob lub hydrogens txuas, ua rau steric hinderance yuav luag tsis yog. Yog li peb tuaj yeem pom tias nws muaj ob lub zog uas yuav nyiam nucleophilicity, tab sis nws tsis yog qhov zoo tshaj plaws nucleophileYog li thaum tsis muaj nucleophile zoo dua, cov dej molecule tuaj yeem ua raws li nucleophile.

Puas H2O yog electrophile?

Dej yog ib electrophile . Nws ua raws li electrophile raws li txhua lub atom hydrogen muaj qhov zoo (◊+) nqi. Tsis tas li ntawd, nws coj zoo li electrophile li dej molecule tuaj yeem tso cov proton thiab tsim ib daim ntawv cog lus nrog nucleophile.
