qauv ntawm Cov Khoom Siv Muaj Zog Hydrogen Lub zog ntawm hydrogen bonds feem ntau yog vim muaj kev cuam tshuam electrostatic. Cov ntawv cog lus OHO muaj zog tshaj plaws yog nyob rau hauv ionic systems, txij li electrostatic attraction ntawm dipole thiab monopole feem ntau ntau dua ntawm ob dipoles.
Dab tsi muaj H daim ntawv cog lus muaj zog?
Cov nyiaj muaj zog hydrogen koom nrog hom ionic. Piv txwv suav nrog Cl−⋯H2O, F−⋯H 2O, H3O+ ⋯H2O, F−⋯HF nrog kev sib cuam tshuam lub zog ntawm kwv yees li 15, 30, 35, thiab 40 kcal / mol, feem. Nyob rau hauv cov ntaub ntawv ntawm qhov kawg complex, daim ntawv cog lus muaj zog heev uas lub complex kuj yuav muab faib ua ib tug chemically bonded.
Puas hydrogen bonding tsis muaj zog lossis muaj zog?
Cov nyiaj hydrogen uas feem ntau yog los ntawm 5 txog 30 kJ / mol yog qhov muaj zog dua li kev sib cuam tshuam ntawm van der Waals, tab sis tsis muaj zog dua covalent lossis ionic bonds.
Puas yog daim ntawv cog lus hydrogen muaj zog heev?
Hydrogen bonds yog muaj zog intermolecular rog tsim thaum lub atom hydrogen bonded rau lub electronegative atom mus txog ib qho ze electronegative atom. … Daim ntawv cog lus hydrogen yog ib qho ntawm cov muaj zog tshaj plaws kev sib tshuam, tab sis tsis muaj zog dua li covalent lossis ib daim ntawv cog lus ionic.
Qhov twg yog daim ntawv cog lus muaj zog tshaj plaws?
In chemistry, covalent bond is the strongest bond. Nyob rau hauv xws li kev sib raug zoo, txhua ntawm ob lub atoms sib koom electrons uas khi lawvua ke. Piv txwv li, cov dej molecules yog sib koom ua ke qhov twg ob qho tib si hydrogen atoms thiab oxygen atoms sib koom electrons los ua ib daim ntawv cog lus.
