Delocalization ntawm electrons txo qis tus nqi, nce kev ruaj ntseg. Cov kua qaub nrog lub hauv paus conjugate uas tau delocalized electrons vim resonance yog acidic ntau dua li cov kua qaub nrog lub hauv paus conjugate nrog cov khoom siv hauv zos.
Puas delocalization nce hauv paus?
No delocalization nce kev ruaj ntseg ntawm lub hauv paus. Kev ruaj ntseg ntau dua ua rau qis qis dua. Lub hauv paus uas muaj resonance delocalization ntawm cov electron khub uas tau koom nrog cov proton yuav yog li ntawd yooj yim dua li lub hauv paus tsis muaj qhov tshwj xeeb no.
Puas ruaj khov nce acidity?
Vim tias cov kua qaub tau dhau los ua qhov tsis zoo thaum poob ntawm cov proton, kev ruaj ntseg ntawm tus khub tshiab ntawm lub hauv paus conjugate yog qhov tseem ceeb hauv kev txiav txim siab seb qhov kev sib haum xeeb yuav zoo li cas. Hauv lwm lo lus: txhua yam uas stabilizes lub hauv paus conjugate yuav nce acidity
Puas resonance nce acidity?
Teb luv luv: Cov qauv kev sib hloov uas khov kho lub hauv paus conjugate yuav nce acidity.
Puas benzene nplhaib nce acidity?
Txawm hais tias cov no yog txhua tus me me resonance contributors (tsis zoo nqi yog muab tso rau ntawm cov pa roj carbon ntau dua li cov electronegative oxygen), lawv tseem muaj tseem ceeb cuam tshuam rau cov acidity ntawm phenolic proton. Qhov tseem ceeb, lub nplhaib benzene yog ua raws li pawg electron rho tawm los ntawm resonance.
