H2S, H2Se thiab H2Te nthuav tawm dipole-dipole intermolecular rog thaum H2O nthuav tawm hydrogen bonding. Hauv qhov no, hydrogen bonding ntawm cov dej muaj zog dua li qhov tawg ntawm H2Te.
Puas hydrogen sulfide puas muaj hydrogen bonding?
Piv txwv li, xav txog hydrogen sulfide, H2S, ib lub molecule uas muaj tib yam li dej tab sis tsis muaj hydrogen bonds. … Txawm hais tias N–H lossis O–H pawg tuaj yeem tsim cov ntawv cog lus hydrogen nrog lwm cov molecules, pawg S–H ua tsis tau.
Yuav ua li cas lub zog cuam tshuam ua haujlwm ntawm ob lub hydrogen sulfide molecules?
(a) H2S molecule:
Raws li VSEPR txoj kev xav, qhov no txhais tau hais tias cov duab ntawm cov molecule yog khoov thiab vim yog cov duab asymmetrical, cov molecule yog polar. Lub zog intermolecular uas polar molecules koom nrog yog dipole-dipole rog.
Dab tsi rog tuav hydrogen sulfide ua ke?
15) Cov dej molecules ntsib hydrogen bonds whereas hydrogen sulfide (H2S) molecules kev dipole rog.
Vim li cas hydrogen sulfide muaj dipole-dipole rog?
H2S nthuav tawm dipole-dipole intermolecular rog. sulfur yog electronegative ntau tshaj li hydrogen thiab ua rau cov molecule me ntsis polar thiab khoov zoo li tus. Lub khoov zoo ntawm cov molecule ua rau vectorial sum ntawm daim ntawv cog lus dipole lub sij hawm yuav tsim ib tug tsis-zero.
