Acetone yog ib tug polar molecule vim nws muaj polar bond, thiab cov qauv molecular ua tsis yog vim li cas dipole kom muab tso tseg. Tsis muaj lwm yam dipole tshem tawm C-O dipole . Xaus: Themolecule ispolar.
Hauv qhov no, acetone puas muaj lub sijhawm dipole?
Hauv acetone , qhov tshwm sim ntawm C-Hbond dipole moments (txawm tias me me) ntxiv rau C = O dipolem kev . B. Daim ntawv cog lus C-H dipole moments ntawm acetone yog qhov loj dua li C-Cl daim ntawv cog lus dipolemments ntawm phosgene. D. Phosgene muaj thaum tetrahedralgeometry acetone muaj ib tug trigonalgeometry.
Kuj Paub, puas yog acetone muaj zog intermolecular tsis muaj zog? Acetone muaj qhov tsis muaj zog intermolecularforces , yog li nws evaporated sai tshaj plaws. Acetone ua tsis koom nrog hydrogen bonding, yog li nws intermolecularforces yog piv tsis muaj zog , thiab evaporates feem ntau sai.
Dhau li ntawm qhov no, hom dab tsi ntawm lub zog ntawm acetone muaj?
Teb thiab piav qhia: 1) Acetone yog adipolarmolecule. Yog li ntawd, lub dominant intermolecularforces nruab nrab ntawm acetone molecules yog dipole-dipoleinteractions. London dispersion zog muaj nyob nruab nrab ntawm txhua tus hom ntawm molecules, uas tuav lawv cov moleculestogether.
Puas yog acetone muaj hydrogen bonds?
Acetone ua tsis yog muaj hydrogenbonding vim tias tsis muaj hydrogens sib txuas ncaj qha rau theoxygen uas yuav muab lub zog xav tau ntawm dipole
Pom zoo:
Puas yog acetone muaj lub sijhawm net dipole?
Hauv acetone, qhov tshwm sim ntawm C-Hbonddipole lub sijhawm (txawm tias me me) ntxiv rau C = O.dipolemoment. B. C-H daim ntawv cog lus dipole lub sij hawm ntawm acetone muaj ntau dua nyob rau hauv qhov loj dua C-Cl daim ntawv cog lus dipolemoments ntawm phosgene
Puas yog ch3 muaj lub sijhawm dipole?
Ib tug molecule zoo li fluoromethane, CH3F, muaj ib tug mus tas li dipole. Nco ntsoov tias tseem muaj cov dipoles hauv C-H daim ntawv cog lus, tab sis lawv tsawg dua li cov hauv C-F daim ntawv cog lus uas lawv tsis muaj teeb meem. Tag nrho cov dipole muaj ib tug buildup ntawm tsis zoo nqi ntawm cov fluorine
Puas yog n2 dipole dipole?
(c) NH3: Hydrogen Bonding dominates (txawm hais tias muaj dispersion thiab dipole-dipole rog ib yam nkaus). (b) TSIS muaj qhov kub siab dua vim tias nws muaj dipole-dipoleforces, qhov N2 tsuas muaj zog tawg. (c) H2Te muaj qhov kub siab dua li H2S. Ob leeg muaj dispersion thiab dipole-dipole rog
Cov nonpolar molecules puas muaj dipole dipole rog?
Cov tsis muaj polar molecules puas tuaj yeem pom muaj zog dipole-dipole? Dipole-dipole rog tshwm sim thaum qhov zoo ntawm cov polar molecule yog attracted rau qhov tsis zoo ntawm ib tug polar molecule. Nyob rau hauv ib tug nonpolar molecule, tej zaum yuav tseem muaj polar bonds, nws tsuas yog hais tias lub dipoles tshem tawm ib leeg
Dab tsi yog qhov txawv ntawm dipole dipole thiab London dispersion?
Thaum tag nrho cov molecules yog attracted rau ib leeg, qee qhov kev nyiam muaj zog dua lwm tus. Tsis-polar molecules yog attracted los ntawm London dispersion attraction; polar molecules yog attracted los ntawm ob qho tib si London dispersion quab yuam thiab lub zog dipole-dipole attraction
