Hydrogen bonding tuaj yeem tshwm sim ntawm hydrogen thiab plaub lwm yam. Oxygen (feem ntau), Fluorine , Nitrogen thiab Carbon. Cov pa roj carbon yog qhov tshwj xeeb uas nws tsuas yog sib cuam tshuam hauv hydrogen bonding thaum nws raug khi rau cov ntsiab lus electronegative heev xws li Fluorine thiab Chlorine.

Ib yam li ib tug yuav nug, cov ntsiab lus twg tuaj yeem koom nrog hydrogen bonding Vim li cas hydrogen tshwj xeeb hauv kev sib cuam tshuam zoo li no?

Cov khoom siv hluav taws xob zoo li oxygen, nitrogen , thiab tshuaj fluorine tuaj yeem koom nrog hauv hydrogen bonding. Hydrogen yog tshwj xeeb nyob rau hauv hom kev sib cog lus vim hais tias cov nyiaj tau los ntawm hydrogen atom nyob rau hauv ib tug polar bond thiab electronegative atom.

Ib yam li ntawd, dab tsi ntxiv yog qhov tsim nyog kom muaj hydrogen atom nyob rau hauv ib lub molecule los koom rau hauv ib daim ntawv cog lus hydrogen? Crystal lattice yuam kom tsis tshua muaj kev sib haum xeeb ntawm molecules.

Ntawm no, dab tsi cov ntsiab lus ua hydrogen bond nrog?

Hydrogen bonding tshwm sim tsuas yog nyob rau hauv molecules qhov twg hydrogen yog covalently bonded rau ib ntawm peb lub ntsiab: tshuaj fluorine , oxygen , los yog nitrogen . Peb lub ntsiab lus no yog electronegative heev uas lawv tshem tawm feem ntau ntawm cov electron ceev hauv covalent daim ntawv cog lus nrog hydrogen, tawm hauv H atom heev electron-tsis muaj.

Puas muaj hydrogen bonds nyob qhov twg?

Ib qho piv txwv ntawm a hydrogen daim ntawv cog lus yog pom nruab nrab ntawm cov dej molecules. Nyob rau hauv ib tug discrete dej molecule, muaj ob hydrogen atoms thiab ib tug oxygen atom.
