Phenol yog acidic ntau dua ethanol vim phenoxide ion ntau ruaj khov tshaj ethoxide ion vim resonance.

Raws li txoj cai, phenol puas acidic dua li ethanol?

Phenols muaj ntau acidic ntau dua li cawv vim hais tias tus nqi tsis zoo nyob rau hauv phenoxide ion tsis yog nyob rau hauv cov pa atom raws li nws yog nyob rau hauv ib tug alkoxide ion tab sis yog delocalized raws li nws yog sib koom los ntawm ib tug xov tooj ntawm carbon atoms nyob rau hauv benzene nplhaib.

Tom qab, lo lus nug yog, uas yog acidic cawv ntau dua los yog phenol thiab yog vim li cas? Phenol yog ntau acidic vim tias thaum nws poob ib H + ion nws tsim phenoxide ion uas ruaj khov (resonance stabalised). Tab sis cawv tsis muab H + ions yooj yim los tsim alkoxide ion uas tsis ruaj khov thiab nkag tau H + ion thiab daim ntawv. cawv dua.

Ib tug kuj nug, vim li cas phenol acidic dua ethanol?

Hauv phenol , rub lub pz electrons los ntawm cov pa atom rau hauv lub nplhaib ua rau cov hydrogen atom yog ib feem zoo. tshaj Nws yog nyob rau hauv aliphatic cawv. Qhov no txhais tau tias nws yooj yim dua ploj ntawm phenol tshaj Nws yog los ntawm aliphatic cawv, yog li ntawd phenol muaj zog dua acidic vaj tse tshaj ethanol.

Vim li cas phenol acidic?

EXPLANATION: Lub acidity ntawm phenols yog vim nws muaj peev xwm poob hydrogen ion los tsim phenoxide ions. Hauv ib phenol molecule, lub sp2 hybridised carbon atom ntawm benzene nplhaib txuas ncaj qha mus rau hydroxyl pawg ua raws li ib tug electron tshem tawm pawg.
