12.38 Nws muaj tus siab dua vapor siab (a) C2H6 los yog C4H10 : C2H6 muaj tus siab dua vapor siab. Muaj tsuas yog dispersion rog, thiab cov no muaj zog nyob rau hauv lub hnyav dua C4H10 molecule. Nyob rau hauv cov ntaub ntawv zoo li no, lub hnyav molecules, uas muaj muaj zog dispersion rog, yuav muaj tus siab kub taw tes.
Yog li ntawd, puas yog c3h8 lossis c4h10 muaj qhov kub siab dua?
C2H6 < C3H8 < C4H10 . Tag nrho cov tshuaj no yog nonpolar thiab xwb muaj London dispersion rog: qhov loj dua lub molecule, qhov loj dua lub zog dispersion thiab lub siab dua tus kub point.
Ib yam li ntawd, qhov twg yuav muaj qhov kub siab dua? Lub zog txheeb ze ntawm plaub lub zog sib txawv yog: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion rog. Kev cuam tshuam ntawm txhua qhov kev ntxim nyiam zog yuav nyob ntawm cov pab pawg ua haujlwm tam sim no. Cov ntsiab lus kub nce raws li cov pa roj carbon ntau ntxiv.
Kuj paub, qhov chaw twg koj xav kom muaj qhov kub siab dua?
Qhov muaj zog ntawm lub zog intermolecular, lub siab dua tus kub point . Feem ntau, hydrogen bonding muaj zog dua li dipole-dipole attractions, uas yog muaj zog tshaj London dispersion rog.
Yuav ua li cas koj txiav txim siab boiling point?
Boiling-Point Elevation Piv txwv
- Glucose yog peb cov kua dej thiab dej yog qhov hnyav.
- Kb rau dej yog 0.51 degrees Celsius kg / mol.
- Molar mass ntawm qabzib yog 180 g / mol.
- Cov dej kub npau npau yog 100 degrees Celsius.
- Qhov sib npaug rau qhov siab ntawm qhov siab yog delta T = mKb.

Qhov twg muaj qhov kub siab tshaj plaws CCl4 cf4 lossis CBr4?
Qhov nyob ntawm tus naj npawb ntawm electrons. CBr4 muaj 146, piv nrog 42 hauv CF4 thiab 74 hauv CCl4. CBr4 yog qhov kub siab tshaj plaws
Puas yog ethane lossis ethene muaj qhov kub siab dua?
Ethane muaj zog intermolecular attractions (van der Waal lub zog) dua li ethene thiab yog li muaj qhov kub siab dua
Qhov twg los thawj qhov ntev lossis qhov dav lossis qhov siab?
Dab tsi los ua ntej? Graphics 'kev lag luam tus qauv yog dav los ntawm qhov siab (dav x qhov siab). Txhais tau hais tias thaum koj sau koj qhov ntsuas, koj sau lawv los ntawm koj qhov kev xav, pib nrog qhov dav. Qhov ntawd tseem ceeb
Cov kua methanol lossis ethanol twg muaj qhov vapor siab dua ntawm chav tsev kub?
Methanol muaj qhov loj dua vapor siab nyob rau hauv chav tsev kub vim hais tias nws muaj qis molecular hnyav thaum piv nrog ethanol, uas txhais tau hais tias nws muaj zog intermolecular zog
Puas yog ethanol lossis acetone muaj qhov kub siab dua?
Yog li, ethanol (nrog rau H-bonding peev) yuav tsum muaj qhov kub siab tshaj plaws, nrog polar acetone muaj qhov kub siab tshaj plaws tom ntej, thiab cov nonpolarpropane, nrog lub zog tsis muaj zog ntawm lub cev, yuav muaj qhov kub siab tshaj plaws. 41
