Feem ntau hais lus, aromatic molecules tsis yog acidic kiag liTab sis lub tswv yim ntawm aromaticity tuaj yeem ua rau qee cov molecules ua acidic. … Raws li kuv hais, cov tshuaj tsw qab tsis yog acidic. Cov pKa ntawm benzene uas yog koj cov tshuaj tsw qab tshaj plaws, yog tias koj cov tswv cuab, 44.
YPuas muaj ntxhiab los yog Antiaromatic ntau acidic?
Cov tshuaj tsw qab yog ruaj khov dua li cov tshuaj tsw qabNyob rau hauv ib qho anion ntawm compound A, 4π electrons yog delocalising. Thaum peb muab n=1, hauv 4nπ formula peb tau 4π. Yog li, anion ntawm compound A yog anti-aromatic yog li, lub compound A yuav tsis plam proton yooj yim vim yog anti-aromatic cim, A tsis yog acidic.
Puas yog aromatic txhais tau tias acidic?
Lub hauv paus ntawm kev sib txuas A ua rau muaj ntxhiab tsw qab deprotonation: Qhov no yog qhov tseem ceeb ntawm cyclopentadienyl anion derivative, uas muaj 6 π electrons uas yog delocalised hla lub nplhaib. Yog li no cov compound yuav yog by deb tshaj acidic.
YPuas yog benzene yog cov kua qaub lossis lub hauv paus?
Benzene yog a hauv paus vim nws muab ib khub electrons.
Yuav ua li cas acidic tshaj?
Ib tus superacid muaj cov kua qaub ntau dua li cov ntshiab sulfuric acid. Lub ntiaj teb lub zog superacid yog fluoroantimonic acid. Fluoroantimonic acid yog sib xyaw ntawm hydrofluoric acid thiab antimony pentafluoride.
