Dab tsi yog resorcinol?
Resorcinol yog ib qho organic compound nrog cov tshuaj formula C 6 H 6 O 2. Nws yog ib qho ntawm peb lub isomeric benzenediols uas yog dawb thiab soluble hauv dej. Nws tseem hu ua Resorcin lossis m-Dihydroxybenzene. Nws yog 1, 3-isomer ntawm benzenediol.
YPuas resorcinol acidic lossis yooj yim?
Resorcinol tsuas muaj -Kuv cov txiaj ntsig thiab tsis muaj qhov cuam tshuam electron-dawb, uas ua rau nws tshaj plaws acidic.
Puas resorcinol muab iodoform kuaj?
Nws tau muab rau hauv kuv phau ntawv uas tsis yog cov tshuaj sib xyaw ib txwm uas teb iodoform xeem, resorcinol (benzene-1, 3-diol) kuj muab cov tshuaj iodoform zoo.
Yuav ua li cas resorcinol siv rau?
Resorcinol yog siv los kho pob txuv, seborrheic dermatitis, eczema, psoriasis, thiab lwm yam kab mob ntawm daim tawv nqaij. Nws kuj yog siv los kho pob kws, calluses, thiab warts. Resorcinol ua haujlwm los ntawm kev pab tshem tawm tawv, tawv nqaij, lossis tawv tawv.

Puas yog tag nrho cov tetrahedral molecules nonpolar?
Txhua 100% symmetrical tetrahedral molecule yuav tsis muaj polar . Tetrahedral molecules tsis muaj cov khoom siv hluav taws xob tsis sib txuas electron khub Lone khub muaj nyob hauv lub plhaub sab nraud ntawm lub plhaub ntawm cov atoms. … Electron khub yog li ntawd suav hais tias yog ib leeg khub yog tias ob lub electrons raug ua ke tab sis tsis siv rau hauv kev sib txuas tshuaj.
Puas yog dolostone yog pob zeb lossis tsis yog?
Dolostone zoo ib yam li limestone, tab sis feem ntau yog cov ntxhia dolomite (CaMg (CO3)2). Ob leeg yog pob zeb sedimentary uas tshwm sim li nyias mus rau cov txaj loj ntawm nplua-rau pob zeb coarse-grained. Lawv cov xim feem ntau yog qee qhov ntxoov ntxoo ntawm grey, tab sis tej zaum yuav yog dawb, tan, daj, liab, ntshav, reddish xim av, xim av, los yog dub.
Tau trigonal bipyramidal puas yog nonpolar?
Trigonal Bipyramidal Piv txwv Nonpolar. ob txoj haujlwm axial tsis zoo ib yam. peb txoj haujlwm equitorial yog tib yam. Puas yog trigonal bipyramidal molecule polar? POLARITY: POLAR - Ib khub electrons pov tseg qhov zoo kawg nkaus tshem tawm symmetry ntawm tsib trigonal bipyramidal cheeb tsam yog li ua rau tag nrho cov molecule polar.
Puas yog nacl yog polar molecule?
Sodium Chloride (NaCl) uas yogionic compound ua raws li cov polar molecule. Feem ntau, qhov sib txawv loj hauv electronegativities hauv sodium thiab chlorine ua rau lawv daim ntawv cog lus polar. … Lub caij no, yog tias muaj ions tam sim no ces cov tebchaw feem ntau yuav yog polar nyob rau hauv qhov.
Puas yog ligroin polar lossis nonpolar?
Vim ligroin yog a nonpolar hnyav(muaj 6-carbon alkanes), nonpolar qauv molecules yuav yooj yim yaj hauv cov kuab tshuaj thiab tsis adsorb rau polar silica gel. Ib yam li ntawd, polar qauv molecules yuav adsorb rau cov silica gel nyob ruaj ruaj.
