Ntau precisely, qhov zoo thiab tsis zoo nqi ntawm hydrogen thiab oxygen atoms uas tsim dej molecules ua rau lawv attracted rau ib leeg . Sib nqus ncej nyiam ib lwm zoo li zoo them atoms nyiam negatively them atoms nyob rau hauv dej molecules.

Xav txog qhov no, dab tsi ua rau cov dej molecules sib nyiam?

Hydrogen Bonds Cov nqi sib tw nyiam ib lwm . Qhov zoo me ntsis nqi ntawm hydrogen atoms hauv a dej molecule nyiam me ntsis tsis zoo nqi ntawm cov pa atoms ntawm lwm cov dej molecules . Lub zog me me ntawm kev nyiam hu ua hydrogen bond.

Qhov thib ob, yog vim li cas dej yog ib tug polar molecule? A dej molecule , vim nws cov duab, yog a polar molecule . Ntawd yog, nws muaj ib sab uas tau them nyiaj zoo thiab ib sab uas raug them tsis zoo. Cov molecule yog tsim los ntawm ob lub atom hydrogen thiab ib qho oxygen atom. Cov kev sib txuas ntawm cov atoms hu ua covalent bonds, vim hais tias cov atoms sib koom electrons.

Tom qab ntawd, lo lus nug yog, yuav ua li cas molecules nyiam ib leeg?

Atoms nrog tus nqi zoo yuav yog nyiam rau negatively charged atoms tsim ib molecule . Qhov kev sib txuas ntawm atoms no yog tus yuam sij rau yuav ua li cas molecules cuam tshuam nrog ib leeg . Positioning ntawm atoms nyob rau hauv a molecule tuaj yeem muab nws polarity.

Vim li cas adhesion tshwm sim hauv dej?

Cohesion tuav hydrogen bonds ua ke los tsim qhov nro ntawm qhov chaw dej . Txij li thaum dej yog attracted rau lwm cov molecules, nplaum zog rub dej mus rau lwm cov molecules.
