Cawv yog ib qho organic compound uas nws cov molecule muaj ib lossis ntau pawg hydroxyl uas txuas ntxiv rau cov pa roj carbon atom. Phenol , ntawm qhov tod tes, yog ib qho kev sib xyaw ua ke ntawm cov pab pawg hydroxyl sib txuas ncaj qha mus rau pawg muaj ntxhiab hydrocarbon. Phenols yog cov xim tsis muaj xim nyob rau hauv daim ntawv ntawm crystals.
Ib yam li ntawd, vim li cas phenol tsis yog cawv?
Cov cim electron rho tawm ntawm pawg phenyl ua phenol acidic ntau dua li qub cawv . Piv txwv li, phenol tuaj yeem muab rho tawm los ntawm cov kuab tshuaj organic rau hauv cov kua dej NaOH vim yog tsim ntawm NaOPh. Qhov no yuav tsis yog tshwm sim nrog ib tug raug cawv zoo li 1-octanol.
Ib sab saum toj no, puas yog phenol thawj cawv? Phenols yog cov molecules uas muaj ib pawg -OH uas txuas ncaj qha rau lub nplhaib benzene. Cawv tuaj yeem muab faib ua thawj , theem nrab, lossis theem nrab. Qhov kev faib tawm no yog nyob ntawm seb tus cawv carbon txuas rau ib, ob, lossis peb pawg alkyl. Phenol yog me ntsis soluble hauv dej.
Ua raws li qhov xav tau, puas muaj phenol muaj cawv hauv nws?
phenols . A phenol muaj ib qho -OH sib txuas rau unsaturated sp2 carbon. Yog li ntawd, nws ua tsis tsim nyog raws li ib tug cawv . Ib tug tuaj yeem faib nws ua ib qho enol, txawm li cas los xij.
Dab tsi ua haujlwm pab pawg yog phenol?
Phenyl yog ib pab pawg ua haujlwm nrog lub nplhaib uas muaj ntxhiab sib txuas rau lwm pab pawg. Thiab, phenol yog ib qho molecule uas tsuas yog ib phenyl ua ke a pawg hydroxyl . Txawm li cas los xij, qee qhov chaw suav tias phenol nws tus kheej yog pab pawg ua haujlwm.

Puas yog cawv yog sib tov lossis sib xyaw?
Technically, cawv yog lub npe ntawm cov khoom siv hauv chav kawm uas muaj ib lossis ob peb pawg hydroxyl.Anazeotrope [] yog sib xyaw ntawm ob lossis ntau dua cov kua dej uas tsis tuaj yeem hloov pauv los ntawm kev distillation yooj yim. Lwm cov khoom lag luam, xws li isopropanol thiab acetone
Puas yog cawv yog cov tshuaj dawb huv lossis sib xyaw?
Ntshiab hydrogen yog ib yam khoom ntshiab. Cov cawv dawb huv tuaj yeem yog ethanol, methanol, lossis sib xyaw ntawm cov cawv sib txawv, tab sis sai li sai tau thaum koj ntxiv dej (uas tsis yog cawv), koj tsis muaj cov tshuaj dawb huv lawm
Puas yog cov cawv thawj zaug ua rau HCl?
Tertiary alcohols teb sai sai nrog cov concentrated hydrochloric acid, tab sis rau thawj lossis theem nrab cawv cov tshuaj tiv thaiv qeeb heev rau cov tshuaj tiv thaiv tseem ceeb heev. Ib qho dej cawv tertiary reacts yog tias nws yog shaken nrog concentrated hydrochloric acid nyob rau hauv chav tsev kub
Puas yog ammonium nitrate soluble hauv cawv?
Ammonium nitrate, yog xim tsis muaj xim rhombic lossis monoclinic siv lead ua nyob rau hauv chav tsev kub. Nws tuaj yeem decomposed rau hauv dej thiab nitrous oxide ntawm 210 ° C. Nws yog soluble hauv dej, methanol thiab ethanol
Vim li cas ethyl cawv muaj qhov kub siab tshaj li methyl cawv?
Ethanol muaj qhov kub siab dua li Methanol.Li no, yuav tsum muaj lub zog ntau dua los kov yeej cov kev sib cuam tshuam, ua rau muaj qhov nce hauv boiling / meltingpoints
