Dr. Haxton hais rau nws chav kawm tias a dej molecule tau ua 4 hydrogen bonds , tag nrho cov nyob rau hauv tib lub dav hlau raws li peb atoms.

Ib yam li ntawd, nws raug nug, pes tsawg atoms hauv cov molecule hauv qab no tuaj yeem koom nrog hydrogen bonding nrog dej?

Txhua dej molecule tau form ob hydrogen bonds koom nrog lawv hydrogen atoms ntxiv ob ntxiv hydrogen bonds siv cov hydrogen atoms txuas rau cov neeg nyob sib ze dej molecules . plaub no hydrogen bonds optimally teem lawv tus kheej tetrahedrally nyob ib ncig ntawm txhua dej molecule raws li pom hauv cov dej khov zoo tib yam (saib txoj cai).

Ib yam li ntawd, yuav ua li cas yog tias dej tsis tsim hydrogen bonds? Hydrogen bonds ua kom qhov txo qis ntawm qhov kub siab tshaj plaws hauv lub cev loj ntawm dej . Txawm li cas los, tsis muaj hydrogen bonds , dej hauv dej hiav txwv thiab pas dej yuav pib sai sai vim qhov poob ntawm qhov kub npau npau - ua rau muaj teeb meem loj rau lub neej hauv ntiaj teb.

Tsis tas li ntawd, hom ntawv cog lus twg yog dej?

Dej yog ib tug polar molecule A dej molecule yog tsim thaum ob atoms ntawm hydrogen daim ntawv cog lus covalently nrog ib tug atom ntawm oxygen. Hauv covalent daim ntawv cog lus electrons sib koom ntawm atoms. Hauv dej kev sib koom tsis sib npaug. Cov pa oxygen atom nyiam cov electrons ntau dua li cov hydrogen.

Puas yog ch4 yog hydrogen bond?

Teb thiab piav qhia: CH 4 tsis tuaj yeem tsim hydrogen bonds . Qhov no yog vim hydrogen bonds yog ib hom kev sib cuam tshuam electrostatic, uas tsuas yog ua tau nyob rau hauv molecules nyob rau hauv uas
