Hydrogen bonds yog feem ntau muaj zog dua tshaj Van der Waals zog. Cov no bonds yog ntev thiab zoo nkauj heev. Van der Waals cov rog yog ua raws li cov dipoles ib ntus uas tsim thaum cov molecules nyob rau hauv lub xeev ntawm flux los yog txav.

Ua li no, puas yog hydrogen daim ntawv cog lus tsis muaj zog lossis muaj zog dua Van der Waals rog?

Cov hydrogen daim ntawv cog lus (5 txog 30 kJ / mole) yog muaj zog dua a van der Waals kev sib tham, tab sis qaug zog dua covalent los yog ionic daim ntawv cog lus . Hom no daim ntawv cog lus tuaj yeem tshwm sim hauv inorganic molecules xws li dej thiab hauv cov organic molecules zoo li DNA thiab cov proteins.

Ib yam li ntawd, puas yog hydrogen daim ntawv cog lus van der Waals? Hydrogen bonding yog hom thib peb ntawm van der Waals ' zog. Nws yog tib yam li dipole-dipole kev sib cuam tshuam, nws tsuas yog tau txais lub npe tshwj xeeb. A hydrogen daim ntawv cog lus yog dipole dipole kev sib cuam tshuam uas tshwm sim ntawm ib qho molecule nrog a daim ntawv cog lus nruab nrab a hydrogen atom thiab ib qho ntawm oxygen / fluorine / nitrogen.

Ib yam li ntawd, covalent bonds muaj zog dua Van der Waals?

Hauv kev sib raug zoo, covalent bonds yog cov muaj zog tshaj , ua raws li ionic, hydrogen daim ntawv cog lus , Dipole-Dipole Interactions thiab Van der Waals zog (Dispersion Forces).

Yam khoom twg muaj zog dua ionic lossis covalent lossis hydrogen?

Covalent bonds muaj zog dua tshaj ionic daim ntawv cog lus . Hydrogen bonds tshwm sim ntawm ob lub atom ntawm hydrogen . Bonding yooj yim tshwm sim ntawm nonpolar thiab polar molecules.
