Qhov kev nyiam ntawm tus kheej cov dej molecules tsim ib daim ntawv cog lus hu ua hydrogen bond … Ib qho dej molecule muaj ob lub hydrogen atoms. Ob qho tib si ntawm cov atoms tuaj yeem tsim ib daim ntawv cog lus hydrogen nrog oxygen atoms ntawm cov dej sib txawv. Txhua lub molecule dej tuaj yeem ua hydrogen sib txuas nrog txog li peb lwm cov dej molecules (Saib daim duab.
Puas yog dej covalent lossis hydrogen bond?
Ib tus dej molecule muaj ob atoms ntawm hydrogen txuas los ntawm covalent bonds rau tib lub atom ntawm oxygen. Atoms ntawm cov pa oxygen yog electronegative thiab nyiam cov electrons sib koom hauv lawv cov ntawv cog lus.
Vim li cas dej yog daim ntawv cog lus hydrogen?
Nyob rau hauv dej molecules cov pa atom attracts lub negatively them electrons ntau zog tshaj hydrogen Qhov no muab dej asymmetrical faib ntawm nqi kom nws yog ib tug polar molecule. … Vim hais tias cov dej molecules me me, lawv muaj peev xwm nyob ib puag ncig ib molecule ntawm cov kuab tshuaj thiab tsim hydrogen bonds.
Dab tsi yog hom kev sib txuas ntawm hydrogen?
Hydrogen bonding yog ob hom, thiab nws tau muab cais raws li hauv qab no: Lub Intramolecular Hydrogen Bonding . The Intermolecular Hydrogen Bonding.
Yuav ua li cas koj tawg daim ntawv cog lus hydrogen?
Hydrogen bonds tsis muaj zog, tab sis lawv ua rau cov dej molecules lo ua ke. Cov ntawv cog lus ua rau cov dej molecules koom nrog ib leeg. Tab sis cov nyiaj no tuaj yeem tawg tau los ntawm tsuas yog ntxiv lwm cov khoom rau hauv dej.
